Introduce

This 268 grams box bottom zipperlock bag is highly appreciated in the consumer market for dry nuts, which is able to provide a strong and eye-catchting sachet for the products. The standing ability of the package makes it possible to include the product effectively at the point of sale.  This zipperlock pouch is very practical for handling and can be produced with a high volume like 300 grams，500 grams，1000 grams or even 2000 grams .

Here we are going give a further explaination on this box bottom zipperlock bag, and hope it helps you to decide your perfect packaging.

Foil Structure

This foil materials is a reinforced structure with excellent properties for spices powder packages. The foil structure is BOPP18/VMPET12/LDPE, with graphic as below.

BOPP18, is short for biaxially orientated polypropylene film with most common thickness 18 microns (equals to 0.72 gauge). After biaxial orientation process, BOPP film is enable with good mechanical strength, excellent printability, high clarity, and mechanical property, which enables it a fine print substrate film in flexible packaging area.

VMPET12, means vacuum metallized polyester film with thickness 12 microns (equals to 0.48 gauge), is the most common used aluminum metallized films in flexible packaging field. It is with high barrier performance against mositure 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 film, means low density polyethylene film, which is the most used inner sealing layer for the coffee bag. It is able to provide enough sealing strength and airtight property for the final packages.

The final thickness for this foil laminate should be 135 microns, with tolerance +-5%. and the toughness of this foil will be enough to finalize good package profile for 268 grams of dry nuts.

 Standup Doypack Properties

1 Great print quality

The artwork is achieved in gravure printing which can print up to maximum 10 colors. With advanced print techniques and print defects inspection system, we are now outputing fantastic print effect against the customers’ artwork.

2 Great Standing Profile

Using three layers of composite foil material, the package can show a beautiful reinforcement effect when filled with 268 grams of dry nuts. This bag can stand on the shelf independently,so customers can better see  the design of the bag.

3 Excellent Airtight Property for Zipperlock

This single track plastic zipper is applied onto the flat bottom doypack, with back and front part well melted to the inner layer of the doypack.  It enables the package to be repeatedly opened and closed with great airtight property.If the customer does not use up this time can close the zipper lock,wait until the next time when the need to open.

Here, we are going to open and close the zipperlock for several times, and check if the air is easy to penetrate into or out of the package. Usually, we will apply a certain pressure on this closed zipper doypack, and check if the inflated doypack is easy to burst.

You are advised to have a further understanding on this test progress through the video below.

4 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, upon 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 an more easy and reliable method to check if the bag strength is enough to meet the various conditions in the operations of filling, transport, loading and unloading, distribution. 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 fill 1000grams of coffee beans into this kraft paper foil pouch, and perform drops for 5 times, and check if there is any breakage for the package.

You are advised to watch the video below.

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

5  Easy Tear from the tear notch

Usually, there is tear notch applied on one or both sides of the doypack, so when the doypack is well sealed, the consumers can just easily open the package through this notch.

Some customers may like to get a perfect tear on their package, and usually linear tear materials or laser scored line should be the ideal solution, as you can see the linear straight tear effect from the laser scored line on this dry nuts doypack, perfect

You may watch the video below to understand how this laser scored doypack be easily torn into straight line.

Package Dimension and Filled Level

Artwork Printing

More Sustainable Options

With increasing burden on the plastic pollution, more and more products are now seeking for packages which are more sustainable, like compostable packages, recyclable mono materials packages, plant-based materials packages. They all proves to be more eco-friendly than the traditional multilayer packages which are even very difficult to be recycled.

1) Home compostable film material packages

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

The compostable substrate films are as below.

1. BOPLA Film
2. PLA+PBAT Film
3. Kraft Paper
4. Metallized Paper
5. Cellulose Paper
6. Metallized Cellulose Paper
7. PBS Film

Based on the compostable substrate film, we are developing kinds of multi-functional packages for various applications, as below

1. High barrier performance packages, for roasted coffee beans, nutritions, milk powder, snacks or biscuits.
2. Alkaline resistant packages for hand wash, laundry cleaning chemicals etc
3. Frozen packages, like fish, noodles, or soup products
4. Vacuum packages for vegetables, rice, red beans etc
5. Hot filling packages for juice
6. Microwave packages

Along with the extentions of compostable film materials, more and more products are now starting to get well packed in home compostable packages, with some well-applied foil structures as below.

Biodegradable Foil Laminate	WVTR (g/m2/24hr)	OTR (cc/m2/24hr)
BOPLA40/PLA+PBAT60	62.2	267
Cellulose30/PLA+PBAT60	131.5	5.6
Kraft Paper45g /PLA+PBAT60	44	742

2) Mono Materials Recyclable Pouch Packages

Mono meterials pouch packages are truly recyclabled, 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 be processed, as PET and LDPE are quite different material, 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 materials pouch are basically divided into Polyethylene channel and Polypropylene channel, with polyethylene channel much more popular, as they can be converted into kinds of standup pouch packages with relative 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
5. LLDPE Film
6. CPE Film
7. ABOPP Film
8. CPP Film
9. VMCPP Film
10. VMBOPP Film

Various foil laminates can be achieved based on above film materials with different properties, which is intended to meet the particular requirements for specific product. Some foil laminates are well-known as below.

1. MDOPE/APE
2. MDOPE/LDPE
3. MDOPE/EVOH-LDPE
4. MDOPE/HDPE/APE
5. MDOPE/BOPE/APE
6. BOPE/APE

Upon our experience, mono materials pouch can be well intended for spices powder products.
