摘要: A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

摘要: A plastics moulding process is provided in which a first (2) and a second plastic part (3) are moulded such that a contact surface is formed between the two parts. The first part (2) is moulded firstly and, whilst at least the contact surface is still in a liquid or plastic state, an attachment promoting powder (16) that is compatible with, and has the characteristic of attaching to, the plastic of the first part (2), is applied to it. Thereafter, the second part (3) is moulded so as to contact the first part at the contact surfaces such that as it solidifies, it attaches to the attachment promoting powder (16) and thereby to the first part (2). The second part (3) may be a plastic foam filling for a hollow first part (2). The attachment promoting powder (16) may be a suitable grade of diatomaceous earth or a natural or synthetic equivalent.
