摘要:
A label film laminate has a carrier and a label film that can be released from the carrier and can be punched and imprinted. The label film is based on a single-layer or multi-layer extrusion film of polyethylene, whereby the extrusion film has a film thickness of less than 85 μm, and is made up of, at least in outer zones, on both sides, of a high-density polyethylene (HDPE) having a density of more than 0.950 g/cm3.

摘要:
The present invention is directed to an unitized cover and transfer layer for hygiene applications that have the appearance, strength, and drape of a nonwoven and the surface characteristics of a film. The lightweight apertured film surface the present invention is comprised of a series of void spaces that act to collect liquids and channel such liquid into an associated underlying absorbent layer, while reducing potential release of particulates inherent to the absorbent layer. Further, the unitized cover and transfer layer of the present invention exhibits significantly reduced frictional noise and discomfort induced by prolonged contact.
摘要:
High density polyethylene made using a cobalt or iron complex of a selected tridentate ligand as a polymerization catalyst may be made into packaging which has advantageous properties, especially lower permeation to ambient materials such as oxygen and/or water. The packaging, such as bottles, bags and rigid storage tanks, may be formed by conventional methods.

A weatherstrip for automotive and motor vehicle window glass comprises a glass contact layer overlying a base extrusion. The base extrusion is formed of a thermoplastic vulcanizate (TPV) comprising ethylene-propylene diene polymer (EPDM) and polypropylene. The glass contact layer is formed of a material composed predominantly of a thermoplastic polyolefin polymer and comprising a silicone-crosslinked thermoset polymer. The thermoset polymer may be the reaction product of a silane-grafted polyolefin and a silicone polymer.
摘要:
The present invention relates to a structure comprising, successively: a first layer of high density polyethylene (HDPE), a layer of binder, a second layer of EVOH or of a mixture based on EVOH, optionally a third layer of polyamide (A) or of a mixture of polyamide (A) and polyolefin (B). The present invention also relates to devices for transferring or storing fluids and more particularly tubes, tanks, chutes, bottles and containers consisting of the above structure and in which the barrier layer (the second or the combination of the second and the third layer) is in direct contact with the fluid contained or transported.
摘要:
Moisture and gas permeable ionomeric films are described. The films described herein are obtained from blends of ionomers with an organic acid salt in the amount of at least about 5 wt %, and have MVTR greater than films obtained from conventional ionomers. Particularly preferred are the potassium salts of stearic, oleic, isostearic, and isooleic acids. Films comprising a liquid-absorbent ionomer film layer and an impermeable layer are provided. The films are suitable for preparation of tubular casings and shrinkbags, in particular, casings for smoked foodstuffs.
摘要:
The present invention provides a slipsheet and/or divider sheet and a method for making the same, the sheet having an imprint or an embossing that provides a raised planar surface. The raised planar surface preferably comprises a plurality of ridges, crowns or crests, which are preferably arranged in a pattern throughout an upper surface of the sheet. To make the sheet, a die can be etched to have protuberances or bumps, and the die is preferably pressed into a sheet of pliable thermoplastic material. The sheet thus made has a plurality of indentation formed by the protuberances or bumps on the die, and the sheet has a planar outer surface comprising a plurality of ridges, crowns and crests between the indentations.

The present invention provides a reinforced thermoform or blow-molded article, and the process for preparing the same, where the reinforcement is provided by a fiber-reinforced thermoplastic composite that contains a thermoplastic resin, such as a rigid thermoplastic polyurethane, and a plurality of continuous reinforcing fibers impregnated with the resin. The reinforced thermoform blow-molded article is useful in a variety of products such as boat hulls, table tops, automotive and non-automotive seat structures, small vehicle structures such as golf carts and golf cart roofs, pallets, containers, and skis.
摘要:
A resealable container is provided having a container opening and a rim and a multilayer film covering the container opening and the rim. The multilayer film contains at least an outer layer, a sealing layer facing the rim and a layer of adhesive between the outer layer and the sealing layer. The sealing layer is secured around the rim and contains a weak spot such that when the resealable container is first opened a double bead of said sealing layer remains on the rim in the region of the weak spot. Such resealable containers have improved tear-open behavior and resealability.
摘要:
A cling film system includes first and second film piles having different composition. Each film ply includes at least one cling layer and, desirably, one or more additional layers. Each film ply includes an overlapping portion and a second portion. The cling layer of the first film ply engages the cling layer of the second film ply in the overlapping portion of the first film ply and in the overlapping portion of the second film ply.
