The design and material selection of seafood packaging bags are crucial. In order to ensure that the freshness and taste of seafood are not affected during transportation, these packaging bags usually use advanced material technology. For example, some packaging bags use new PE materials, which are moisture-proof, waterproof, insect-proof and have good sealing properties, which can effectively prevent odor transfer and preserve freshness. In addition, there are composite materials such as PET/PE, PET/CPP, etc. These materials not only have good sealing properties, but can also withstand certain pressure and deformation. Different types of seafood also have different packaging requirements.For example, individual packaging bags for ready-to-eat sea cucumbers are usually made of PA+PE materials, and the thickness and color can be customized according to needs. For frozen seafood, three-side sealed freezer bags are a common choice and are suitable for food that needs to be stored in low-temperature environments. , seafood packaging bags are not only simple containers, but also a key tool to ensure the quality of seafood and extend its shelf life.
