Abstract
A machinable flexible packaging material capable of forming a seal that is reclosable at ambient temperature is made by applying a tacky adhesive and a thin skin layer onto a substrate, such as polyester film. Being thin, the skin layer fractures when the seal is opened, thereby allowing the adhesive to form a resealable interface at the seal area. However, since the adhesive is encapsulated in the material initially, the material may be used like other packaging materials in form, fill and seal machines.
