Lock & Peel™ (Polyolefin Polymer)

Developed by Du Pont-Mitsui Polychemicals Co., Ltd., Lock & Peel™ resin is a new material that produces either a complete seal or an easy-to-peel feature depending on the heat sealing temperature at the time of manufacturing the package.
With these features, the material is increasingly used for packages that have two separate compartments, for food and cosmetics.
A two-compartment bag refers to a form of packaging where two different contents are packed in a single unit.
With Lock & Peel™, two different contents can be separately preserved in a single package, and they can be mixed together in a single operation at the time of use.
This provides users with a pleasant experience of change caused by mixing the two different contents. It is highly rated as a new package with experience value and helps prolong the expiration date and reduce food losses.Furthermore, it embodies the universal design concept in the form of mixing through a single operation in many applications.

<Horizons of Material>

• ● Two seal statuses can be achieved with a single material. It is proposed for a new single package preserving and carrying different contents that can be mixed together in a single operation at the time of use.
• ● It extends the expiration date of the content, increases convenience and adds new experiential value to the package.
• ● The combination of the two seal statuses with the value of the package design in terms of experience will expand the horizons towards creating new products.
