POLYMER FILM FOR IN-MOULD LABELLING
The invention relates to a multi-layered, opaque, biaxially-oriented polyolefin film with a thickness of less than 150 mum and which comprises f. a base layer that contains vacuoles and at least one polymer of at least one olefin, g. an inner intermediate layer that contains at least one polymer of at least one olefin, h. an outer intermediate layer that contains at least one polymer of at least one olefin, i. an inner cover layer which is in contact with the inner intermediate layer and contains 5-70 wt. % of at least one polyethylene and 30-95 wt. % of at least one propylene polymer, and j. an outer cover layer which is in contact with the outer intermediate layer and contains 5-70 wt. % of at least one polyethylene and 30-95% of at least one propylene polymer, each amount indication relating to the weight of the layer in question, and characterised in that said outer intermediate layer has a thickness of 0.5 to 5 mum and contains 4.5 to 30 wt. % of pigments, preferably Tau[Iota]Omicron2, in that the outer cover layer has a thickness of >0 to <2 mum, and in that the film has a gloss on either side of less than 50 gloss units measured according to DIN EN ISO 2813 at an angle of 60 DEG and at a temperature of 25 DEG C.

Liner structure and blow-molding manufacturing method forliner structure
A liner structure includes a liner main body and an insert located inside an opening of the liner main body. The liner main body is made of a polybutylene material. The liner structure has relatively good heat resistance within a temperature range corresponding to conventional liquid water, and can be used for containing hot water. Moreover, a feasible manufacturing method is provided. The method can overcome defects of material characteristics through process optimization, so that can implement manufacturing the liner structure.
CONTAINER AND PACKAGING SYSTEM
A method for manufacturing packaging comprises the steps of: temperature conditioning one or more selected portions of at least one preform; and blowing and/or stretching the at least one temperature conditioned preform into a blow mold to form a container including an offset neck finish. Containers, packaging systems and packaging products are disclosed.
LABELED CONTAINER AND METHOD FOR MANUFACTURING SAME
The method for manufacturing a labeled container includes disposing an in-mold label, including the following (a) or (b), heating a preform, inserting the preform into a mold, and blow molding by expanding the preform to form a labeled container. (a) Making the one direction substantially coincide with a horizontal direction when the size of the labeled container with respect to the size of the preform is 2 times or more in a horizontal direction and 1 time or more and 2 times or less in a depth direction. (b) Making the one direction substantially coincide with a perpendicular direction when the size of the labeled container with respect to the size of the preform is 1 time or more and less than 2 times or more in a horizontal direction and 1 time or more and 2 times or less in a depth direction.
