A heat-sealable multi-layer film structure charactised by consisting essentially of:

• (i) an outer heat sealable layer (A), a core layer (B), and an outer layer (C), the outer heat sealable layer (A) being coextensively adherent to the upper surface of the core layer (B), and the outer layer (C) being coextensively adherent to the lower surface of the core layer (B)
  
  said outer layer (A) being formed from a polymer composition (a) consisting essentially of heat sealable resin compounded with one or more slip additives which are incompatible with polypropylene.
• (ii) said core layer (B) being derived from a polymer composition (b) consisting essentially of an isotactic polypropylene homopolymer compounded with one or more slip additives which are incompatible with polypropylene, and
• (iii) said outer layer (c) being formed from a polymer composition consisting essentially of isotactic polypropylene homopolymer in the substantial absence of slip additives;

A vacuum insulation panel (10) comprising a defined dual layered enclosure (1) encasing a defined compressed fiberglass substrate (3) which enables easy and effective insulation of large equipment with improved system flexibility and integrity.

The present invention relates to an improved container for citrus juices and other liquids. The container utilizes a paperboard barrier laminate (34, 36, 38, 40) for the containment of essential oils and the prevention of losses of Vitamin C. Also disclosed is a process of making the laminate. The laminate makes use of a layer (40) of a heat-sealable ethylene vinyl alcohol copolymer to enhance the barrier properties of the laminate.

Structures à couches polymériques multiples comprenant une couche en polymère du fluorure de vinyle ou de vinylidène liée à une couche en polymère polaire à l'intervention d'un polymère d'acétate de vinyle.

Les structures à couches polymériques multiples peuvent se présenter sous la forme de films, de feuilles, de plaques, de tubes ou de corps creux utilisables notamment dans le domaine de la protection contre la corrosion ou les rayons ultraviolets.

A method of packaging ovenable fish or meat and which comprises the steps of providing a dual-ovenable thermoformable polymeric receiving film having a first and second surface and a dual-ovenable polymeric covering film having a first and second surface, wherein said receiving film consists of a mono-layer polyester or polyamide substrate, an optional barrier layer, and an optional heat-sealable layer which where present constitutes the first surface of the receiving film, wherein said receiving and covering films are separate pieces of film and wherein at least one of said first surfaces of said receiving and covering films is a heat-sealable surface; providing a raised outer portion and an indented central portion in said receiving film by thermoforming; disposing on the first surface of the receiving film a portion of meat or fish; disposing the covering film over the portion of meat or fish such that the first surface of the covering film is disposed towards the first surface of the receiving film; contacting the peripheral portions of the first surface of the receiving film and the first surface of the covering film and forming a heat-seal bond therebetween; and optionally freezing the packaged meat or fish is described.
