CONT

Aluminium barrier foils are available in a wide range of specifications and can be manufactured to suit individual requirements. They derive their protective properties from a strong construction. They [are comprised] of 2, 3 or 4 layers of different materials, bonded together with adhesive or extrusion polyethylene.... The middle layer is aluminium, which acts as a barrier to prevent water vapour, oxygen and aggressive gasses from entering the pack. This [construction] is the key to the aluminium barrier foil' s performance in preventing [the] deterioration of products.

Les films barrières en aluminium sont disponibles dans une large gamme de spécifications et peuvent être fabriqués pour des exigences individuelles. Ils doivent leurs propriétés protectrices à leur structure solide. Ils se composent de 2, 3 ou 4 couches de matériaux différents, liées entre elles [avec] de l'adhésif ou du polyéthylène extrudé. [...] La couche intermédiaire est en aluminium, et [elle] agit comme une barrière à la vapeur d'eau, à l'oxygène et aux gaz agressifs. Elle constitue la clé de la performance du film barrière en aluminium et [elle] empêche la détérioration des produits.

Other blow molding operations.... Fluorination surface treatment is a process to improve the gas barrier of polyethylene to nonpolar solvents. A barrier is created by the chemical reaction of the fluorine and the polyethylene, which form a thin(20-40 nm) fluorocarbon layer on the bottle surface. Two systems are available for creating the layer. The "in-process" system uses fluorine as a part of the parison expand gas in the blowing operation. The "post-treatment" system requires bottles to be placed in an enclosed chamber filled with fluorine gas. The method forms a barrier layer on both the inside and outside surfaces. This surface treatment allows low-cost, blow-molded polyethylene bottles to be used for paint, paint thinner, lighter fluid, polishes, cleaning solvents, cosmetics, and toiletries. The approach can replace other higher cost resins or coextrusion processes.

DEF

A class of solid or semi-solid products of synthetic origin, having barrier properties when used in multilayer applications.

OBS

If the product to be contained is an aqueous product, an internal layer of a good water-vapor barrier is needed, eg., polyethylene(PE), polypropylene(PP), or PVDC. If the product is a relatively nonhygroscopic material, a nylon, PET or PVC can be used.

OBS

Products such as plastic bottles and trays make use of barrier resins.
