A packaged product has a product surrounded by a vacuum skin package. The vacuum skin package has a support member and an implosion-resistant thermoplastic top web. The top web conforms with both the upper surface of the product, and an uncovered portion of the upper surface of the support member. The thermoplastic top web comprises an ethylene/α-olefin copolymer in an amount of from 55 wt % to 85 wt %, based on total weight of top web, and/or a blend of ethylene/α-olefin copolymer and cyclic olefin copolymer. Also disclosed is a vacuum skin package containing the implosion-resistant top web.

Inflation and sealing device with web control

The present disclosure is directed to a web control guide for an inflation and sealing assembly of a protective packaging formation device for inflating a web material into a chain of inflated cushions. The web control guide is positioned along a material path at a transverse spacing from a first compression element and constrains a first thickness of the material path measured normal to the longitudinal and transverse directions of the material path. The transverse spacing and constrained thickness dimension are sufficiently small to prevent transverse movement of the flexible material towards the first compression element to avoid excessive heating of the web material outside a sealing zone.
