Abstract:
A sheet (2) is made by the method of the invention, in particular for use for the punching of lids for containers, in that a PE layer (5a) and a polyester (PET) welding layer (5b) of an amorphous polyester are applied to a base sheet layer (4) of polyester (PET) by coextrusion to form the finished sheet laminate (2). This ensures that the sheet (2) is transparent throughout, just as it provides the possibility of controlled delamination by separation of the PE layer (5a) from the PET welding layer (5b) in the welding area only, when the sheet (2) is pulled off a container (1). In addition, the sheet does not curl when punched into lids prior to being applied to the containers (1).
Abstract:
The present invention relates to the use of HDPE as a contact layer of laminate films, wherein layer, optionally coextruded, comprising a contact layer and at least one tie layer is adhered to a base layer, as well packagings making use of the laminate films to wrap often liquid formulated agrochemical sub- stances.
Abstract:
A method for making a sheet laminate for being pre-punched to a sheet lid for a container, comprising the steps of providing a base sheet layer, and coextrusion coating an additional sheet layer, which comprises a tie layer comprising polyolefin and a welding layer comprising polystyrene (PS), onto said base sheet layer, so that the tie layer is disposed between the base sheet layer and the welding layer.The additional layer is coextrusion coated onto the base sheet layer.A sheet lid with a similar structure may be manufactured by punching the sheet laminate.The sheet lid may be used to close a container to form a package.
Abstract:
The present invention relates to a method for providing an extreme chemical resistant film whereby a tie layer and a contact layer are coextruded with a base layer, such as a metal foil, as well as films and laminates obtained by the method and uses of the films and laminates to pack aggressive chemical substances such as nicotine, lidocaine, fentanyl and rivastigmine.
Abstract:
A method for extrusion coating or extrusion casting, a polymer sheet (4, 5) produced thereby, a roller (2) for use in extrusion coating or extrusion casting, and an apparatus comprising said roller (2), in which micro- and/or nanostructures provided on the surface of the roller (2) are transferred to the polymer sheet (4, 5), and which is applicable to the extrusion coating or extrusion casting of all types of thermoplastic polymer.
Abstract:
The invention relates to a blister pack comprising a lower web (1) in which cavities (2) are provided, and an upper web (4) which is welded to the lower web (1). The upper web (4) is welded to the lower web (1) in a rim area (6) around the cavity (2), whose extent may be varied to ensure the force necessary for the separation of the layers. Thus, this may be adapted as needed, and thereby, as regards child resistance, a certain great force is required, while a rheumatic patient pack will require less force and thereby a narrower rim area (6).
Abstract:
The present invention relates to a lid for welding on and closing a package, preferably a disposable package of a polymer material, said lid comprising a PET sheet with a thickness from 23 to 50 μ, on one side of which a metallized layer is applied, said metallized layer having applied thereon a COEX coating in an amount of from about 10 to about 25 g/m 2 , said COEX coating containing a polymer which is selected to as to be compatible with the polymer material in the package.
Abstract translation:本发明涉及一种用于焊接和封闭包装的盖子,优选地是聚合物材料的一次性包装,所述盖子包括厚度为23至50微米的PET片材,其一面涂敷金属化层, 所述金属化层在其上涂覆有约10至约25g / m 2的COEX涂层,所述COEX涂层含有选择为与包装中的聚合物材料相容的聚合物。
Abstract:
The present invention relates to a blister package (1) consisting of a lower web in which a row of cavities (3) is provided, and an upper web (12) which is welded to the provided lower web, and wherein perforation lines (7) are provided between adjoining cavities, and wherein there is an area (6) in connection with each cavity where the upper web is not welded to the lower web, such that a snip is created, said upper web being welded to the lower web by a first inner weld (4) which surrounds the cavity completely, as well as a second outer weld (5) which surrounds the cavity around the first weld and adjoins the area where the upper web is not welded to the lower web. The invention also relates to a method of making the blister package.
