Introduce

This attractive bag is made of MatteBOPP18/VMPET12/LDPE foil material. This is a standup box bottom sachet with a degassing valve for a 500g matte gold standup zipper coffee sachet, which is quite famous in the consumer market for coffee products and young people. The main body is set in gold colors, which attracts so glamorous coffee products and young people.

Here we are going to get a better understanding of this tremendous package, and hope it helps you to choose your perfect packaging.

Foil Structure

Generally, we name the foil structure MatteBOPP18/VMPET12/LDPE, so it can be well understood in business activities. This laminated foil also extends its wide application to many other products, such as pet food, laundry detergent, etc.

Please note, that all the film materials, inks, and adhesives applied in our flexible packaging are certificated human food safety. Then, let’s get into a better understanding of each of the substrate films.

Matte BOPP18, or matte biaxially oriented polypropylene, is a polymer film with a matte finish that absorbs light instead of reflecting it. With a matte finish effect on the outside, Matte BOPP film is widely used to improve visual effects and add a fashionable touch to the packaging.

VMPET 12, which means vacuum metalized polyester film with a thickness of 12 microns (equal to 0.48 gauge), is the most commonly used aluminum metalized film in the flexible packaging field. It has high barrier performance against moisture vapor and oxygen. The barrier performance will enable your coffee products well protected from the roaster warehouse to the consumer’s hand in a fine way.

LDPE means low-density polyethylene film, which is the most used inner sealing layer for coffee bags. LDPE is also lightweight, easy to fabricate, and has good chemical and impact resistance. LDPE is recyclable and reusable, making it a popular alternative to traditional plastic. LDPE is nontoxic, non-contaminating, and has a high degree of break resistance. Most importantly, LDPE membrane can be modified against the requirement of specific products, and finalize the package with great seal strength and protection. The thickness of the LDPE membrane will be decided against the particular application.

The final thickness for this foil laminate should be 140 microns, with a tolerance of +-5%. and the toughness of this foil will be enough to finalize a good package profile for 500 grams of coffee products.

3.1 Great print quality

The artwork is printed through gravure printing on our rotogravure print press which can print up to a maximum of 10 colors. With advanced print techniques and a print defects inspection system, we are now outputting fantastic print results against customers’ artwork.

In our manufacturing plant, we take serious measures to achieve high color fidelity and consistency for repeated print orders, and here we will give an overall introduction.

a.  Color Analyzer

This color analyzer is one of the auxiliary tools in our system to achieve the highest standard for color fidelity. The eXact Advanced doesn’t just validate the color of CMYK and spot color inks, it can simultaneously measure four M modes to visualize the spectral reflectance of a substrate or ink, measure the concentration of a specific ink, and measure the difference of a substrate or ink over white and over black.

b. Pantone Color Code

The Pantone color guide would be so helpful to locate a specific color for the pring service supplier and the customers, especially if there is a large area printed in single Pantone color. For many Pantone colors, the accuracy may be influenced by the printer, paper substrate, and environmental factors when it is printed onto physical photo paper. Pantone Color Code will be located in the artwork design with the customers before the order is put into production.

c. Physically Printed On Photo Paper

Computer files such as JPG, PDF, PSD, AI, etc can not be taken as the guide to determine the color in print produce, as they present the colors through electronic screening devices. Different electronic screens may be set in different parameters by the various manufacturers, which will inevitably interfere with the color presentation. Artwork can only be a reliable guide when printed on the physical substrate, with the most common photo paper applied.

3.2 Barrier Performance

When LDPE film is trapped in this foil laminate the barrier performance is good enough to keep pet food products in fine protection.

3.3 High Mechanical Strength

This reinforced laminated foil is achieved with great mechanical strength, with some standard items as below.

• Tensile Strength
• Sealing Strength
• Anti-puncture Strength
• Burst Impact Strength
• Anti-pressure Property

The above tests are performed against each order, based on customer requirements, and you may check the exact values of this foil material in the Technical Date Sheet part of this post.

In our daily QC work, there is a more easy and more reliable method to check if the bag strength is enough to meet the various conditions in the operations of filling, transport, loading and unloading, and distribution. We perform a drop test against each order, of course, the standard for this drop test should be decided against customer needs.

Here, we are going to fill 500g of coffee beans into this LDPE film pouch, perform drops 4 to 5 times, and check if there is any breakage in the bag.

You are advised to watch the video below.

You can judge from the video, that the package stays well after 4 to 5 drops, really great physical strength.

3.4 Eye-catching Effect

This pack of 500g coffee beans becomes one of the top picks when it just stands on the shelves. People may not help to lay an eye on it when they just browse the products. It surely helps on the product sale.

3.5 High Barrier Performance

As explained previously, this foil laminate is finalized with a layer of thin aluminum metal sheet, which is of the best barrier performance against oxygen and moisture vapor. Usually, the roasted beans should be well protected to keep the original flavor and fragrance for a prolonged period, to enable the beans enjoyed by the end consumers.

3.6 Fantastic Standup Effect

The bottom of this 500g coffee bag is much like a box when the roasted beans are filled, and that will make the package well stand up on the goods shelf, good for branding and sale.

3.7 Great Mechanical Strength

This reinforced laminated foil can greatly protect coffee beans ranging from 100g to 5lb volume.

We perform various inspections and tests to check the mechanical strength of the finished pouch, like drop tests, hard sudden strikes, anti-pressure tests

• Tensile Strength
• Sealing Strength
• Anti-puncture Strength
• Burst Impact Strength
• Anti-pressure Property

The above tests are performed against each order, on customer requirements.

3.8 Smooth Zipper

The tab zipper, also called the rip zipper, enables the coffee pouch easily torn from the tab place, in a straight-line effect and keeps the original integration of the package. You can see the zipper is embedded into the coffee bag in a gorgeous way, without any wrinkles.

3.9 Fine Air-release System

A degassing valve is applied neatly onto the coffee bag, which enables carbon dioxide to be released from the inside package under a pressure of 2~7mbar.

With the development of biodegradable materials, the compostable one-way degassing valve is also available for compostable coffee packages.

4 Quality Control Measures

Serious quality control measures have been taken in our manufacturing plant, to ensure each order is finished meeting the requirements of particular customers. With more than ten years of working experience in this field, we finalize this QC manual standard, to make sure each order is produced following the correct procedure.

Here, please allow us to guide you further into our QC system.

4.1 Manufacturing Traceback

We apply a strict recording system to document the manufacturing details, such as environmental conditions, craftsmanship parameters, production facility conditions, etc, which allows us to trace back whenever there is a problem.

4.2 QC Test Report Against Each Order

There will be a QC test report issued against each order produced in our plant, with some main items of the properties tested and listed. This is an effective way to get the customers settled on their packages, and highly appreciated by our customers.

You may read here to understand the QC test report of this 500ml motor oil sachet order.

4.3 Print Inspection

In our manufacturing plant, the print inspection is always taken and done in a serious way, as we will never allow the customer’s artwork to be achieved in a way that deteriorates their business. On our gravure print press, there is an in-line inspection system that can eliminate more than 98% of the defects in the printing process.

You may check how it works on our control panel.

There is also a supplementary off-line inspection equipment, to allow us to do the print inspection again whenever it seems necessary.

We are now producing spout bags against customer artwork, and we surely love to support the startup and market-testing period for our customers. We will accept a minimum order quantity of 30,000 bags printed against customer artwork design.

4.4 Airtight Property Test

The finished spout pouch should be completely airtight, otherwise the product may deteriorate under the conditions of oxygen and moisture in the environment. The closure will need to be screwed tightly onto the spout during the filling process when it is done at the customer site.

Here, we apply airtight property test on this capped spout pouch under the minus-pressure environment, and this proves to be the most reliable way in our industry to check if the package is completely tight from the air.

You are advised to watch the video below for a further understanding on this test process.

Video Airtight property test #

4.5 Gas Release Property Test

The gas will be released from the inside when the air pressure for the inside is 2~7 mbar than the outside environment. Usually, we will immerse the valve welded bag under the water, and check if the degassing valve works well.

4.6 Drop Test

Drop test should be considered as a very reliable way to check if the coffee bag strength is enough to meet the various conditions, as it copies the way when the products falls off the good shelves, and the finished bag will suffer great sudden shock. In our daily QC work, We perform the drop test against each order, of course, the standard for this drop test should be decided against customer needs.

Here, we are going to drop the filled coffee bag from 1.6m high, for 5 times.

You are advised to watch the video below, for a further understanding.

After 5 drops for each bag, none of them breaks,  all are fine and dandy.

4.7 Hard Sudden Strikes on inflated spout bags

Hard sudden strikes should be taken as a more fierce test method than drop test, as it causes much higher force on inflated packages.

Let’s watch the video to understand how we perform this test in our manufacturing plant.

4.8 Anti-Pressure Test

Pressure-resistance test is another effective method to decide if the final package will serve as great protection for the products, especially liquid products, like household detergent liquids, and windshield washer fluids. For coffee bags, we will perform the anti-pressure test in our daily QC work, to ensure each order is finished with great mechanical strength.

The leakage or breakage of the coffee bag will surely be a disaster, either for the distributor or the manufacturer.  We will never expect this thing happens in our customer’s business.

Sometimes, for easier and faster operation, we may just get one person to stand on the well-sealed and inflated coffee bag, to check if there is any burst of them.

4.9 Easy Screw-Off of the Closure

The closure will need to be screwed off the plastic spout without much strength, otherwise, it may be an obstacle for the old and weak people to use the products. This is put on our checklist in our QC work, and through the below video, you will be able to understand the screw-off test of the closures.

4.10 Laboratory Tests

Laboratory tests are essential to keep us updated with the intrinsic properties of the foil materials which are not visible to the human eyes. It is crucial to gain a thorough understanding of the data about the production of our bags. The craftsmanship can be improved bit by bit to pursue premium quality bags based on thorough analysis and application of these data. You may check more of these tests in the Technical Data Sheet part of this post.

4.11 Third-party Inspection

Third-party inspection is available for all our orders on agreed standards or regulations.

8 More Sustainable Options

With the increasing burden on plastic pollution, more and more manufacturers are now seeking more sustainable packages, like compostable film materials, recyclable mono materials packages, and plant-based materials packages. They all prove to be more eco-friendly and sustainable than the traditional plastic films which are usually derived from fossil chemicals, and very difficult to recycle and break down in the environment.

Here, we are going to share some of the trending sustainable packages for the coffee market.

8.1 Compostable film material packages

Thanks to the fast development of plant-based film materials, we can present the multi-layer standup pouch and roll foils in full compostable and biodegradable options.

 

The compostable substrate films we adapt to convert the multi-layer flexible pouches are listed below.

1. BOPLA Film
2. PLA+PBAT Film
3. Kraft Paper
4. Metallized Paper
5. Cellulose Film
6. Metallized Cellulose Paper
7. PBS Film
8. PVDC Coated Cellulose Film
9. Metalized BOPLA Membrane

We are now achieving multilayer compostable foil materials based on extrusion coating lamination, solvent-free lamination, and dry lamination, and then convert them  into various types of flexible pouches against customers’ requirements.

Some of the common compostable foil structures are listed below.

• Kraft Paper/PLA+PBAT Membrane
• Kraft Paper/BOPLA Membrane
• Cellulose/PLA+PBAT Membrane
• Kraft Paper/PBS Foil Membrane
• Metallized Paper/PLA+PBAT Membrane
• BOPLA/PLA+PBAT Membrane

• Cellulose/Metallized Paper/PLA+PBAT Membrane
• Kraft Paper/Cellulose/PLA+PBAT Membrane
• Kraft Paper/Cellulose/PBS Membrane
• Metallized Paper/Cellulose/PLA+PBAT Membrane

Here, we are going to introduce the main performance of these compostable materials pouches.

a. Compostable

All the film materials we adopt are certificated compostable, under home or industrial conditions, complying with the standards EN 13432 or ASTM 6400.

 

 

 

 

 

 

 

 

 

 

The films will present different biodegradation behaviors under different conditions, such as industrial composting facilities, home and garden conditions, and natural soil conditions.

In most cases, industrial composting will be able to achieve faster biodegradation of the compostable film materials than other composting progress, as it is able to provide better conditions.

Some manufacturers would like to have better biodegradation behaviors of their own compostable packages under natural soil conditions, as in most cases, the abandoned package may not be recycled into human composting facilities.

You may read here to have a better understanding of the break-down progress of our compostable foil laminated materials under the natural conditions in Qingdao, Shandong, North China conditions.

b. High-barrier performance pouches

Through vacuum metallization, PVDC coating, and AlOx/SiOx depositing, the compostable films can be achieved with better barrier performance, such as water vapor transmission rate (short as WVTR) and Oxygen Transmission Rate (short as OTR). Later on, we will combine several layers of the barrier film and convert it into laminate foil, with an improved barrier property for finished packages.models, or soup products

In the below table, we are going to share some barrier data of the most common foil laminates tested on our Mocon permeation tester.

Biodegradable Foil Laminate	WVTR (g/m2/24hr)	OTR (cc/m2/24hr)

c. Alkaline Resistant

We put a certain amount of bleaching powder into the compostable pouches with various foil structures, and placed them in an environment of 40~45 Celsius degrees, to accelerate the aging process of the compostable pouches.

The test result proves the compostable pouches will be fine for packing alkaline products, like household detergent powder, and hand wash cubes.

However, it is not ok for household liquid detergent and other liquid cleaning chemicals.

You may watch the video below for further knowledge on it.

d. Frozen Treatment

The compostable pouches can be well intended for frozen treatment for some food products, and the mechanical property of the frozen pouch still works well as good protection for the products during the transportation and distribution process.

You may watch the video below to study the test in our office.

d. Vacuum Packages

The compostable pouches can be intended for the vacuum packages for products, like milk powder, nutrition products, etc.

f. Hot Filling up to 100 Celsius Degree

The compostable pouch will be fine for the hot filling process, which may work well for juice products.

Watch the video below to learn our test.

g. Microwave Oven Treatment

The compostable doypack can be well intended for microwave oven treatment, such as melting the candle wax, etc.

Please note, that there should not be a metalized film layer in the compostable pouch when it is intended for this microwave treatment purpose.

8.2 Mono Materials Recyclable Pouch Packages

Mono materials pouch packages are truly recyclable, as they can be easily processed into plastic granules which can be used again for other applications. However, for the traditional multilayer laminates, take PET/LDPE for example, it is difficult to process, as PET and LDPE are quite different materials, and can not be melted under the same conditions. That’s why momo materials pouch packages are becoming so widely popular in the packaging field, and highly reputed in the consumer market.

At present, mono-material pouches are divided into Polyethylene channels and Polypropylene channels, with polyethylene channels much more popular, as they can be converted into kinds of standup pouch packages with relatively high performance.

Here we list the film materials that can be well intended for mono-materials recyclable pouch packages.

1. MDOPE Film
2. BOPE Film
3. APE Film
4. LDPE Film
