Nacheng has many years of experience in the business of making China Heat Shrink bags, we always believe that packaging is not merely about wrapping a layer of film, but rather providing a reliable protective shield for the product, to ensure this reliability, we never compromise on raw materials, we only select base materials that meet national food-grade standards. Our production workshop is managed in accordance with clean-level requirements, and even in the testing process, we have added additional tests simulating storage and transportation.
The Heat Shrink Bag series includes many different products, the Food Vacuum Heat Shrink Bag first evacuates the air to isolate it, and then makes the bag body tightly adhere to the surface of the food through heat shrinkage, it can not only inhibit the growth of bacteria, but also reduce the damage from bumps during transportation. For products like pickled foods, sausages, and fresh meat, using it can extend the shelf life by more than double compared to ordinary packaging.
The EVOH Barrier Heat Shrink Bag adds an EVOH barrier layer, significantly enhancing its oxygen and water vapor barrier performance, it is highly suitable for products such as cheese, imported meat, and ready-to-eat meals that have high requirements for the preservation environment.
