Abstract: An absorbent pad structure particularly suited for use in a vacuum package for a food product and the like is disclosed as well as its method of manufacture. The composition of the pad is such as to minimize leakage of liquids into the absorbent material during storage and to permit the flow of liquids freely for absorption during cooking of the packaged product. The pad is particularly suitable for use in bacon packages and other food packages containing oils or grease.

Abstract: A package for meat products and other oily foods and similar products marketed in stores and suitable for use to heat or cook the contents by microwave radiation comprising a absorbent insert having as basic elements a cooking surface of waxed paperboard or the like and an absorbent underlay. The cooking surface on which the food is laid is provided apertures so that fats and liquids released from the food during cooking may readily pass therethrough and be captured by the absorbent underlayer.

Abstract: A multilayer film is prepared by coextruding nylon with a chemically modified polyolefin which has functional groups added to the basic polymer to provide strong adhesion to the nylon after coextrusion. The multiple layer film combines the strength and protection properties of the nylon with desired properties in the modified polyolefin. Multiple layer films may be produced by coextruding nylon layers with multiple layers of the modified polyolefin, and with additional layers of nonmodified polyolefins and other polymers. Suitable commercially available modified polyolefins for use in the multilayer film include Plexar-1 and Plexar-3 described in U.S. patent application Ser. No. 616,035, and Plexar-2 described in U.S. patent application Ser. No. 616,374, both filed in September, 1975, now abandoned, and respective continuation-in-parts thereof Ser. No. 808,080, now U.S. Pat. No. 4,087,588, and Ser. No. 808,079, now U.S. Pat. No. 4,087,587.

Abstract: A resin blend for producing a peelable heat seal, which does not produce "angel hair" upon separation, includes polybutylene and a copolymer of ethylene with, for example, vinylacetate or methyl acrylate. Typical substrates are high density polyethylene and nylon.
