Provided is a method for forming a bag around an article, the method comprising: providing an oriented film; cauterizing the film at a temperature sufficient to de-orient a portion of the film to create a cauterized area on the continuous film; placing an article(s) on the film between adjacent cauterized areas; heat-sealing the film around the article(s) such that at least a portion of the film between the heat-sealed area and the article comprises the cauterized area. Also, provided is a form, fill, and seal apparatus comprising a heat sealer and a cauterizer, both having a temperature control, the heat sealer positioned to allow the heat sealer to form a seal between two edges of film having an article wrapped therein, and the cauterizer positioned to cauterize an area of the sealed film in an area adjacent to the sealed edges and the article.

Method for packaging articles using cauterized films to inhibit tearing

A sealable polymeric film structure comprising (a) a core layer including a thermoplastic polymer, the core layer having a machine side and a product side that is on a side of the film opposite from the machine side; and (b) a sealable skin layer positioned on the product side of the core layer, the sealable skin layer including a thermoplastic polymer, wherein an exterior surface of the sealable skin layer has a receding Cahn value of at least about 0.48; and wherein in some heat&#x2014;sealable embodiments, the sealable skin layer sealed to itself has a MST of from about 175&#xb0; F. to about 220&#xb0; F., with a jaw pressure of 20 psi for 0.75 seconds and a minimum acceptable seal strength of 200 g/in at 175&#xb0; F., on a Wrap-Ade&#x2122; Crimp Sealer Model J or K.
