Problems solved by technology

However, such features are not always easy to open or reclose.
However, based on the position of the adhesive relative to the package, the adhesive can sometimes be contaminated by the contained product before the package is opened, or once the package is opened, when product is removed from the package and comes in contact with the adhesive.
This phenomenon can compromise the reclosability of the package.
Some retail packages currently do not offer an easy-open and / or reclosable feature.

Abstract

An easy-open and reclosable package includes a pouch including a discrete strip, between first and second side panels, including a sealing segment, a backing segment, and an intermediate layer including a pressure sensitive adhesive; a first portion of the strip anchored to the first panel at a first location, and a second portion of the strip anchored to the first panel at a second location; a die cut in the first panel defining a die cut segment, so arranged that when the package is opened, the sealing segment is partially removed from the discrete strip, the intermediate layer comprising a pressure sensitive adhesive is partially exposed, and the package can be reclosed by adhering at least one of the first and second panels to the adhesive; and a product in the pouch.

Description

FIELD OF THE INVENTION[0001]This invention relates to an easy-open and reclosable package with a discrete strip and die-cut web, and to methods of making the package.BACKGROUND OF THE INVENTION[0002]Food and non-food products, including produce, snack foods, cheese and the like have long been packaged in containers such as pouches, bags, or lidded trays or formed webs made from various thermoplastic materials such as polyethylene, polypropylene, or polyester (PET). These containers can be formed from a web or webs of thermoplastic material on packaging equipment, using various packaging processes, at a processing / packaging facility. Such equipment and processes includes horizontal form / fill / seal (HFFS), vertical form / fill / seal (VFFS), thermoforming / lidstock, and continuous horizontal packaging (sometimes referred to as Flow-wrap). In each case, the product is manually or automatically placed in a pouch, bag, formed web, tray, etc., the filled container is optionally vacuumized or ga...
