Material of textured vacuum packaging bags

Pattern vacuum packaging bags are the darling of vacuum packaging bag families. Because the pattern vacuum packaging bags are processed using co extruded materials, they do not require solution compounding, have high safety, and can compress small patterns on the surface. During vacuum pumping, microchannels can be formed, making vacuum pumping without blind spots. So, now let's take a detailed look at the material of textured vacuum packaging bags:

Co extruded film is a commonly used material for textured vacuum packaging bags in daily life. It is a multi-layer co extruded stretch film with high barrier properties. The characteristics of co extruded film are described in detail as follows:

Introduction to the characteristics of co extruded film

1. High Barrier: Utilizing different plastic materials with varying barrier properties, co extruded films achieve high barrier effects against oxygen, water, carbon dioxide, odors, and other substances.
2. Strong functionality: resistant to oil, moisture, and high temperature cooking up to 120 degrees Celsius, resistant to low temperature freezing, shelf life, freshness, and odor. It can be used for vacuum packaging, sterile packaging, and inflatable packaging.
3. Low cost: Compared to glass packaging, aluminum foil packaging, and other plastic packaging, co extruded film has a significant cost advantage in achieving the same barrier effect. Due to its simple process, the cost of the produced film products can be reduced by 10-20% compared to dry composite films and other composite films.
4. Flexible structural design: By adopting different structural designs, you can meet your different quality requirements.
5. High strength: Co extruded film has the characteristic of stretching during the processing, and the strength of the plastic can be correspondingly increased after stretching. Plastic materials such as nylon and metallocene polyethylene can also be added in the middle to make it have composite strength higher than general plastic packaging, without delamination or peeling, with good flexibility and excellent heat sealing performance.
6. Small capacity ratio: Co extruded films can be vacuum shrink packaged, with a small capacity and volume that cannot be compared to glass, iron cans, or paper packaging.
7. High safety: no residual solvent pollution problem, green and environmentally friendly.

Common types of co extruded films

(1) High barrier and anti-seepage packaging film

The basic structure is: PA/TIE/PE/TIE/PA/EVOH/PA/TIE/PE

It is used for packaging products with long shelf life, such as various cooked meat products, coffee, tea, essence, spices, food additives, cosmetics, etc. It can also be used for packaging products with strong permeability and corrosiveness, such as petroleum, chemical, pesticide, highly toxic, acid, alkali, salt, etc.

(2) Inflatable and fresh-keeping packaging film

The basic structure is: PE/TIE/PA/TIE/PA/TIE/PE

Used in the field of modified atmosphere packaging for food and inflatable packaging such as balloon wrap.

(3) Fresh meat cling film

The basic structure is: PE/TIE/PA/EVOH/PA/TIE/EVA

For fresh meat refrigeration and preservation of pigs, cattle, and lamb, it is required to immerse in water at 80 ℃ for 1-3 seconds and adhere to the body (or in a hot drying oven when exposed to heat). The product packaging has excellent barrier properties and can be stored at low temperatures below -25 ℃.
