Reclose/Reseal a Growing Trend for Plastic Packaging in Food Applications

摘要

It's probably happened to you. You buy a package of deli meat at the supermarket. You open the package the next day to pack a lunch and press together the open film ends to reseal the package. It looks like it can reseal itself, but it just won't. You might have had the same experience in trying to reclose the lid of a clear PET container of lettuce. It looks like you can close it, but there's no adhesive to create a seal, and reclosure just doesn't happen. After several attempts, you end up taking the remaining contents and toss them into a reusable, re-sealable plastic storage bag. The original packaging goes into the trash.
