Packaging bag for frozen food
For frozen packaged foods, the control of pollution, the barrier properties of packaging materials, puncture resistance, low temperature freezing resistance and the safety of packaging materials are closely related to food safety and corporate reputation. Der Yiing Plastics will select the food-grade materials as the only choice for the selection of materials according to the characteristics of frozen foods, and which will be sent to the inspection agency from time to time to ensure safety.
The contents of the package for frozen food
Next, we will study the contents of the package to confirm the special packaging characteristics that need to be strengthened for different products, such as vacuum bags for packaging shrimps. Because of the frozen state, the sharp angle of the shrimp head is easy to break through the bag and cause pollution. Der Yiing Plastics will use a film with higher puncture resistance to protect the product.

Food Safety Commitment
Food packaging safety is the most important part of food sales. Therefore, we must select food-grade safety materials from the procurement of raw materials. In addition to the safety inspection reports provided by the food packaging film raw materials factory, Der Yiing plastics will also send it to the SGS inspection agency from time to time to confirm that it is in line with food safety. For the raw materials, we always use higher standards so that consumers could enjoy the food safely.
Frozen foods focus on the barrier properties, puncture resistance and low-temperature freezing of packaging materials, and can perfectly lock the delicious food on the packaging materials. Therefore, we choose nylon with better ductility, a material that is co-extruded with PE material according to the characteristics of our customers' frozen products. Its good film ductility allows the acute angle generated by the food after freezing to not penetrate the co-extruded vacuum bag, causing the package to be damaged, thereby affecting the safety of the food. In addition, we use different structures of co-extruded materials according to the contents of the customer's packaging. The different barrier properties of three to eleven layers effectively preserve the deliciousness of frozen foods, enabling customers to perfectly convey the taste of frozen foods, eat and buy with peace of mind.

Multilayer Layers Coextruded blown film is replacing the conventional packing materials like paper, aluminum foil, tin, glass etc. These films are considered for packing purpose because of specific requirement of shelf life and protection to product. With its excellent resistance to puncturing, heat sealability, gas barrier, high mechanical property high bursting strength etc. properties these films are having very good scope for packaging.Co-extruded vacuum bags by using 5 layer, 7 layer, 9 layer and 11 layer mixtures of polyethylene, EVOH and nylon resins which offer long lasting robustness and reliability. These vacuum bags have unique stretching capability, which enables them to store any food item. Co-extruded vacuum bags have good collision resistance and less speed for oxygen transfer. For co-extruded bags high graphic printing is not suitable, it only holds surface printing but on the surface of film the print does not shine much. These vacuum pouches are highly flexible, efficient and functional, and are compatible with all kinds of vacuum machines.Multi layer co extruded film could avoid contamination of ink volatile during lamination, more safety & environment friendly. The enforcement flexibility of vacuum bag, pin hole resistance, extend shelf life through co extrusion process could reduce bursting and leakage problems.
Bopp Pearlized Film or also call cavitated film is made from polypropylene resin as raw material that add calcium carbonate and pearlescent pigment and mix them are used to provide light barrier to the products. Generally Bopp pearl film/cpp of composite structure and Bopp pearl film / PE are often used in cold drink packaging such as Ice cream, heat seal label, sweet food, biscuit and local flavor snack packaging.White Pearlized Cavitated Bopp film, one or two side treated is co-extruded with white core layer in non or heat sealable. It is designed for printing and the simultaneous application of glue on the opposite side it ideal to provide light barrier to product. These films can be used as a single layer or in multi layer laminate as an inner sealant for chocolates, ice cream packaging and Soda drink bottle label.
