Let’s continue about the Sustainable and Practical Packaging for 300g gojiberry Bottom Window Bag: PET/Kraft Paper/LDPE Materials.
Packaging Foil Materials:
The foil materials of this paper box bottom bag is formulated in 3 three layers, with details shown in the figure below
PET Film
From the above graphic, you can learn that the material is made of 3 layers. PET film works as the outside print layer, Kraft paper film working as the middle supportive the eco-friendly, and finally, the LDPE film working as the inner sealing layer, Generally, we describe the foil structure as PET/Kraft Paper/LDPE.
PET film is one of the most widely used printing substrates in flexible packaging. It offers excellent optical clarity, high gloss, strong chemical resistance, and stable mechanical strength. Its exceptional dimensional stability and outstanding printability ensure that customer artwork is reproduced vividly and accurately. These properties not only enhance shelf appeal but also provide reliable structural support to the final package.
In the flexible packaging industry, the most commonly used thickness for PET film is 12 microns, which is equivalent to 0.48 gauge. Therefore, whenever you see references to PET12 or 0.48 g PET, you can understand that they refer to the same material.
Kraft paper
is one of the most commonly used material to increase the eco-friendly and sustainability for the gojiberry. Due to the versatility, like light weight, heavy-duty, durable, tear-resistant, and low cost, it helps the roasters to create value-added packaging and a powerful marketing for their products.
As kraft paper is made from renewable resources, like plants and wood pulp, it is considered recyclable, renewable, biodegradable and compostable, which strengthens the green effect of the food package.
LDPE
LDPE (Low-Density Polyethylene) is one of the most widely used inner sealing layers for stand-up juice pouches. It is lightweight, easy to process, and provides excellent chemical resistance and impact strength. As a recyclable and reusable material, LDPE is also considered a more sustainable alternative to traditional plastics. It is nontoxic, non-contaminating, and offers high durability against breakage.
One of the key advantages of LDPE is its versatility. The film can be customized to meet the specific sealing, strength, and protection requirements of different products. The thickness of the LDPE layer is adjusted based on the intended application to ensure optimal performance.
For products such as liquid detergents, LDPE formulations may require additional modification to resist alkaline corrosion. Since each detergent formula is different, the polyethylene blend must be tailored accordingly to maintain barrier integrity and sealing strength.

Excellent matte finish effect with high transparent window.
you can checck the bags quality with below vedio
Mechanical Property
This bag can 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, on customer requirements.
In our daily QC work, there is a 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, and distribution. We perform a drop test against each order, of course, the standard for this drop test should be decided against customer needs.
More Sustainable Materials Options
Along with the increasing burden of fossil-chemical polymer materials discarded into our environment, there is an unprecedented demand for sustainable packages which leads to a more eco-friendly activity of the business. Upon the recent investigation of the nut market, more and more consumers are more likely to purchase a product that acts toward environmental sustainability.
Compostable Packaging Materials
Compostable packaging materials are very similar to biodegradable materials. In most cases, people may not get a clear understanding of the difference between compostable and biodegradable. Generally speaking, compostable materials are based on biodegradable materials and when they break down, they will not cause harmful elements to the environment.
As to the materials used in our factory, the customers can just consider biodegradable equal to compostable.
The compostable packages are based on plant-based fibers like cellulose, or bio-mass like corn starch, cassava, or sugarcane. The resins derived from these resources are usually named bio-polymer, which can break down into inorganic elements under the functions of algae, bacteria, and other microorganisms.
Premium-quality compostable standup sachets and rolls are produced in our plant, which are intended to meet the particular requirements of every product. You may reach us for further ideas if you are interested in compostable packaging materials.
Fully Recyclable Mono Materials
Compared with the high cost of compostable foil materials, actually fully recyclable materials sachets and rolls are flooding the market for lightweight product packages in the market at much lower prices. Mono materials packages mean each layer of the multi-layer foil is made of the same resin, which can be easily processed in the human recycling system and reused for other applications. This recyclable materials sachet largely reduces the rate of plastic polymer film packages ending in landfills.
