Transparent what are some advantages of vacuum bag

food is closely related to people's health, food hygiene people * * sex as the focus, therefore is especially strict with transparent vacuum bag. In the field of food packaging, plastic composite flexible packaging accounts for a large proportion of the. Experts have made clear that the new direction of the future development of food flexible packaging is to improve the performance of the existing transparent vacuum bag, development of new varieties, improving strength and barrier property, reduce consumption, Thick wall) , reuse, recycling to protect the environment.

transparent vacuum bag can not only strengthen the function of protection of food, but also reduce the amount of plastic, and even can be repeated use. For high barrier property protection of processed foods and vacuum packaging, inflatable packaging, etc. , are usually required to buy the vacuum bags, in multilayer composite material must be more than a layer of high barrier property material, commonly used high barrier property of the material with aluminum foil, nylon, polyester, etc. Plastic bags according to the system can be divided into three edge-sealing bag way, in stereoscopic bottom sealing and sealing and crisps 4 class.

three edge sealing is around the bag sealing, positive and back size are finished size, has a certain integral feeling, design constraints, and before and after the design has a certain continuity. Due to the positive and the back size is consistent, can design a positive first, let the back and front echo. Plate is, back to arrange in the same registering the roller.

the bottom seal is sealed at the back, front size for finished product size, the back into two equal parts, and its width is equal to the sum of the width of the front, is on the back, when the design is usually will unfold, carries on the integration of design, and add 1 cm around each sealing side, is, back at the same registering the roller.
