Details about Ordinary vacuum packaging bag

Principle of vacuum bag
The mildew and spoilage of products are mainly caused by the activities of microorganisms, and most microorganisms need oxygen to survive, and the vacuum bag is used to extract the oxygen in the packaging bag and the product cells, so that the microorganisms lose the “survival environment” “To preserve food.

How to choose the right vacuum bag material?
When it comes to vacuum packaging materials, the essential thing is the classification of materials. The following are the characteristics of materials suitable for vacuum packaging:
One is PET/PE. This material structure is more common in the packaging of quick-frozen food products, with good moisture resistance, cold resistance, and low temperature heat sealing performance, and the production cost is relatively low.
Second, BOPP/PE and BOPP/CPP. The frozen food packaging bags of these two structures have excellent moisture resistance, excellent cold resistance, high tensile strength for low-temperature heat sealing, and good economy. It is worth mentioning that BOPP/PE has a better feel than PET/PE, which is good for product marketing.
Third, PET/VMPET/CPE, BOPP/VMPET/CPE. The three-layer structure packaging bag is stronger and more stable than single-layer and double-layer, and has high barrier performance. In addition, the presence of the aluminum-plated layer also has a prominent advantage in printing performance. However, compared with the above materials, low temperature heat Poor sealing performance, higher cost
Fourth, PA/PE, PET/PA/LLDPE, PET/PA/AL/PE, PA/PE. These four types of material structures are more resistant to freezing and impact, and the PA layer ensures good puncture resistance. The disadvantage is that the production cost is higher, and they are generally used for angular or heavier food product packaging.

Advantages of vacuum packaging bags
High barrier: Co-extrude the film with the high barrier properties of different plastic materials to achieve high barrier effects on oxygen, water, carbon dioxide, and odor.
Stable performance: oil resistance, moisture resistance, low temperature freezing resistance, quality preservation, freshness preservation, odor preservation, and can be used for vacuum packaging, aseptic packaging, and inflatable packaging.
Low cost: Compared with glass packaging, aluminum foil packaging and other plastic packaging, co-extruded film has a greater cost advantage to achieve the same barrier effect. Due to the simple process, the cost of the produced film products can be reduced by 10-20% compared with dry composite films and other composite films. 4. Flexible specifications: it can meet your different needs for different products.
High strength: The co-extruded film has the characteristics of stretching during the processing. After the plastic is stretched, the strength can be increased accordingly. You can also add nylon, polyethylene and other plastic materials in the middle to make it have a composite strength that exceeds the general plastic packaging. Existence of delamination and peeling phenomenon, good flexibility and excellent heat sealing performance.
Small volume ratio: The co-extruded film can be vacuum-shrinked packaging, and the volume-to-volume ratio is close to 100%, which is unmatched by glass, tin cans, and paper packaging.
Pollution-free: no binder is added, no residual solvent pollution problem, green and environmental protection.
Vacuum packaging bag moisture-proof + anti-static + explosion-proof + anti-corrosion + heat insulation + energy saving + single perspective + UV isolation + low cost + small volume ratio + no pollution + high barrier effect.
