Thermoforming machine comprising: a fixed platen (1); a tilting moving platen (2); a fixed half-mould (3) integral with said fixed platen (1), a moving half-mould (4), which is supported by said moving platen (2); an extractor device (5) for extracting thermoformed articles from said moving half-mould (4), wherein said extractor device (5) is actuated by an electric motor (10).
摘要:
A method of manufacturing a plastic container having a curled rim (320) comprises the steps of providing a sheet of plastic material; drawing a portion thereof into a mould (120) to form a bottom and wall (310′) of the container, leaving a surrounding portion of material to form a rim (320) of the container; cutting the rim loose from a remaining portion of material; and curling the rim. In the curling step, an inner part of the rim is supported by a supporting member while an outer part is pressed by a pressing member (230) moving relative to the supporting member for the rim to be bent around the supporting member.

A multi-layer sheet (300) for forming an expanded foam container, the multi-layer sheet comprising a first layer (302) of an expanded foam material comprising a first polyolefin-based material comprising at least one polypropylene-based polymer and a second layer (304) of an unexpanded material comprising a second polyolefin-based material comprising at least one polypropylene-based polymer that is co-extruded, extrusion coated, or laminated on a first side of the first layer.
摘要:
The present invention relates to a hot runner assembly comprising a valve member (16) having a generally annular form to be displaceable through at least an annular portion of the inner flow channel (15) the inner and nozzle gates (21, 19) also form annular openings. The invention also relates to a co-injection moulding assembly comprising the hot runner assembly and a method for producing a ring-shaped or hollow polymeric article.
摘要:
The invention relates to a polymer-coated packaging material, a method of manufacturing the same, and products, such as a disposable drinking cup, made from the material. The packaging material comprises a fibrous base (1) of paper or board, an innermost polymer layer (2) containing a blend of (i) 10 to 25 wt-% of a low-density polyethylene (LDPE) and (ii) 75 to 90 wt-% of a second polyethylene with a higher melt viscosity, said second polyethylene being selected from linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE), and an outer layer (3) of more than 90 wt-% of HDPE. An outermost layer (4) of a polymer blend similar to that used for the innermost layer (2) may be provided for heat-sealing. The layers (2, 3 and 4) may be brought and adhered to the fibrous base (1) by coextrusion. To maximize renewability of the materials HDPE and LLDPE as used for the structure are of biologic origin.
