Before loading the rice is given priority to with common bag, pouch, then with the custom plastic ( Structure: synthetic resin, plasticizer, stabilizer, pigment) The development of the packaging bags, with rice is given priority to with custom plastic packaging bags, so what is the difference between the two?

with sacks, cloth bags of rice, reusable, but because of the large gas permeability, moisture, To prevent the items gone mouldy) , light insulation is poor, prone to mildew and insect pests. Plastic bags commonly used food plastic bags are made from polyethylene film, the film non-toxic, it can be used for holding food. There is also a film for PVC, polyvinyl chloride (PVC) itself is non-toxic, but according to the purpose of the thin film additive is often joined by harmful substances to human body, has a certain toxicity. So this kind of film and made of the thin film bag should not be used for holding food. If you want to identify polyvinyl chloride (PVC) and polyethylene plastic bags, plastic bags available to identify the following simple method. Custom bags are after extraction of custom, and filling the nitrogen, carbon dioxide and other gases. Nitrogen is inert, filling effect, make the custom bag to keep positive pressure, in order to prevent the outside air into the pouch, bag of food plays a protective role. Carbon dioxide, corruption has inhibitory activity role of bacteria and other microorganisms. There are food such as crisp fragile, easy to deformation and oil food, there are sharp edges or high hardness will puncture custom bags of food, such as after a custom inflatable packaging, custom bag inside air pressure is greater than the atmospheric pressure outside packing bag, can effectively prevent food compression breakage, deformation, and does not affect the packaging and printing packaging appearance. In small packaging bags with the custom of the promotion and the development of the supermarket, its scope of application will be more and more widely, some will gradually replace rigid package. And with high separation material EVO, PVD

H C, PE ( Polyethylene)
T, PA, and P
E compounded, PP and other custom bags of rice, has moisture-proof ( To prevent the items gone mouldy) , mouldproof, insect-resistant features with good effect, and the printing design on the rice bags, trademark will be very obvious, text, bar code is clearly visible, so it will be easier to attract customers, promote sales. Aluminum foil bag, also known as vacuum packaging, is based on the principle of atmospheric pressure, the main purpose of the custom bag is oxygen, to help prevent food mildew deterioration. Custom packaging is put inside the bag and food of oxygen in cells with pump removed, making the process of microbial survival environment. Food custom bags also prevent oxidation, make food not stale, metamorphic to reduce the loss of vitamins A and C. Plastic bags is essential items in People's Daily life, are often used to hold other items. Because of its cheap, light weight, large capacity, easy to receive the advantages of widely used, but because of the plastic bag with degradation cycle is very long, difficult faults by some countries ban the production and use. Increased PE ( Polyethylene) T materials such as quality, you can increase rice custom plastic ( Structure: synthetic resin, plasticizer, stabilizer, pigment) The strength of the packaging, improve its compressive strength, cracking resistance. Bags, food bags
