Description

1 Introduction

This impressive 227g pet food bag is created for Glory Land to showcase their premium food treats. The packaging not only highlights the exceptional quality of the product but also provides excellent protection during the filling, transportation, and distribution processes.

In this section, we will provide a more detailed analysis of this remarkable food bag, with the hope that it helps you find the perfect packaging solution for your products.

2 Foil Materials

This foil material is a reinforced structure with excellent properties for dog treats packages. The foil structure is PET/LDPE, with a graphic as below.

Let’s first get a further understanding of each substrate layer material.

PET12, is one of the most commonly used printing substrates in flexible packaging pouches. With great optical clarity, high gloss, good chemical resistance, stable mechanical strength, excellent dimensional stability, and great printability, it can present the customer artwork print in great quality, and also provide great mechanical strength to the final package.

LDPE, means low-density polyethylene film, which is the most used inner sealing layer for noodles 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 LDPE membrane will be decided against particular application.

 

The final thickness for this foil laminate should be 120 microns, with a tolerance +-5%. and the toughness will be enough to present a good standing effect for finished bags.

3 Properties and Quality Assurance

3.1 Exquisite print quality

The artwork is achieved in gravure printing on our rotogravure print press which can print up to a maximum 10 colors. With advanced print techniques and a print defects inspection system, we are now outputing fantastic print effects for the customers’ artwork.

At our manufacturing facility, we implement rigorous measures to ensure high color fidelity and consistency across multiple print runs. In this section, we will provide a brief overview of our approach.

a.  Color Analyzer

This color analyzer is an essential tool in our system, helping us achieve the highest standards of color fidelity. The exact Advanced goes beyond simply validating the color of CMYK and spot color inks. It can simultaneously measure four M modes, enabling it to visualize the spectral reflectance of both substrates and inks. Additionally, it allows us to measure the concentration of specific inks and assess color differences on substrates or inks when viewed over both white and black backgrounds.

b. Pantone Color Code

Pantone color guide would be so helpful to locate a specific color for the spring service supplier and the customers, especially if there is a large area printed in a 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. We will locate the Pantone Color Code with the customers in their artwork design before the order is put into production.

c. Physical 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.

Measures taken to achieve high color fidelity and consistency in reprints

3.2 Excellent Matte Finish Effect

The delicious black rice noodles bag is achieved by coating a layer of matte lacquer over the outside of the PET substrate layer, with great adhesion and uniformity. The lacquer layer is of great scratch resistance, which avoids the small hidden lines when the foil passes through the rollers during the bag-making process.

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

There are also some other options to achieve the matte finish effect for the noodles bag packages, and here you may this post if you are interested.

3.3 Excellent Dimension Stability

There is an increasing requirement for the dimension stability of the noodle bags when the roasters and packers are going to improve the production efficiency with high-speed filling lines. We have quite a good understanding on this and are doing our job to narrow the tolerance of the dimensions for each order produced in our long-term supply. Usually for the noodles bag, the tolerance should be controlled within +-2%, which can run well on most of the high-speed filling machineries in the market.

3.4 Delicate Bag Making

The bag is achieved with delicate details, which can create a perfect impression for the consumers when they pass by the products, and cause them a purchase. Some customers do like to buy a product out of its gorgeous profile.

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 227g noodles 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, and you may check the exact values of this foil material PET12/AL7/PET12/LDPE in the Technical Date Sheet part of this post.

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, with the core items evaluated in it.  It is highly appreciated by our customers.

You may read here to understand the QC test report for an order of 250g and 1000g coffee bags.

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 coffee 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 10,000 bags printed against customer artwork design.

4.4 Airtight Property Test

The finished coffee bag should be completely airtight, to get the products well-protected from oxygen and moisture in the environment. We perform the airtight property test against each order with the device as below.

In actual operation, we will pick up 1 bag every 1,000 pcs, and perform the test following the procedure in our QC manual.

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 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 coffee 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 fast 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 Rip Tear Zipper Test

The tab zipper must be easily ripped in the consumers’ hands, otherwise, the product may not be considered a good one for the consumer experience. Easy use of the products will be surely a measure to maintain the consumers for repeat purchse.

4.8 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.

4.9 Third-party Inspection

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

9 More Sustainable Options

With the growing concern over plastic pollution, more and more manufacturers are turning to sustainable packaging solutions such as compostable film materials, recyclable mono-material packages, and plant-based materials. These alternatives are proving to be far more eco-friendly and sustainable compared to traditional plastic films, which are typically derived from fossil fuels and are challenging to recycle and break down in the environment.

In this section, we’ll share some of the trending sustainable packaging options for the noodles market, highlighting their environmental benefits and how they help reduce the overall ecological footprint.

9.1 Compostable film material packages

Thanks to the rapid advancement of plant-based film materials, we are now able to offer multi-layer stand-up pouches and roll foils in fully compostable and biodegradable options.

Below, we have listed the compostable substrate films we use to convert these multi-layer flexible pouches.

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
