A cover film having at least (A) a substrate layer, (B) an intermediate layer, (C) an adhesive layer, and (D) a heat seal layer having a heat sealable resin, a thermoplastic resin of the (D) heat sealing layer having a mixture of two types of (meth)acrylic acid ester copolymers having different glass transition temperatures and a hydrazide compound, wherein one of the (meth)acrylic acid ester copolymer in the (meth)acrylic acid ester copolymer mixture has a glass transition temperature of −20 to 10° C. and the other (meth)acrylic acid ester copolymer has a glass transition temperature of 40 to 80° C.

Various forms of tabbed sealing members are described along with the laminates from which the sealing members are formed. In some forms, the tabbed sealing members may be considered inverted tabbed sealing members for induction sealing as the induction heating layer is provided in the upper laminate instead of the lower laminate. In this regard, the induction heating layer is positioned further from the heat seal, contrary to conventional tabbed sealing members.

The invention provides a laminated body which contains an environmentally friendly recycled material, has a lamination constitution composed of substantially a single resin type mainly composed of polyester and having a low environmental load, and has required performances such as gas barrier properties, sealability, toughness, and transparency required for a packaging material.

The laminated body is formed by laminating a polyester substrate film containing 50% by weight or more of a polyester resin recycled from PET bottles and a heat sealable resin layer in this order,

wherein the substrate film is a laminated film including an inorganic thin film layer (A) and a protective layer (a) containing a urethane resin on one surface thereof, and

the heat sealable resin layer is formed of a polyester-based resin mainly composed of ethylene terephthalate, and has a piercing strength of 10 N or more and a haze of 20% or less.

Tear and heat resistant foams used in packaging, protective packaging bags and related methods are provided. The tear and heat resistant foam can include a nonwoven substrate, a polyethylene film, and a base layer of polyethylene foam joined together by applying at least one of heat or heat and pressure to the top nonwoven substrate, the polyethylene film and the polyethylene foam to heat the first surface of the top nonwoven substrate to a temperature that is above the melting point of polyethylene film but below the melting point of top nonwoven substrate. The temperature of the polyethylene film rises causing the polyethylene film to melt and bind the top nonwoven substrate to the polyethylene foam to form the heat and tear resistant packaging foam.

This invention relates to a biodegradable film which is particularly suitable for the manufacture of packaging and is also characterised by high level mechanical properties.

A skin material-coated foamed particle molded body includes a skin material made of a polypropylene-based resin molded body and a polypropylene-based resin foamed particle molded body coated with the skin material. The skin material has a multilayer structure including an inner layer adhered to the foamed particle molded body and an outer layer outside the inner layer. The outer layer contains a polypropylene-based resin and a reinforcement fiber. The inner layer contains the polypropylene-based resin and a reinforcement fiber in a lower content ratio than a content ratio of the reinforcement fiber contained in the outer layer or contains the polypropylene-based resin and substantially no reinforcement fiber. An average value of the outer layer thickness ratio to a sum of the outer and inner layer thicknesses is 0.20 or more and 0.65 or less, and a coefficient of variation Cv of the ratio is 30% or less.

Robust multi-purpose, multi-layer, building construction tapes and building construction framing members and related wall assemblies are disclosed that comprise a sheet metal framing member (all profiles) in combination with a new and more robust type of multi-layer building construction tape for fire safety and sound reduction. The multi-layer building construction tape comprises a flexible thermal barrier layer attached to (1) a flexible intumescent material layer having a lesser width (thereby enabling flex-lock rollover) and/or (2) a resilient unfoamed cross-linked polyethylene layer. In combination, the thermal barrier layer is on a surface of the sheet metal framing member, whereas the thermal barrier layer is attached to the intumescent layer or polyethylene layer (as the case may be) such that the thermal barrier layer is between the sheet metal framing member and the intumescent layer or the polyethylene layer. The multi-layer building construction tapes disclosed herein slow and impede the spread of fire and smoke (during a fire) and also reduces sound transmission between adjacent rooms in a building.

A shrink film may include at least one layer comprising a blended ethylene-based polymer composition, the blended ethylene-based having a PCR content varying from greater than 5 to less than 95 wt % and a virgin resin content varying from greater than 5 to less than 95 wt %, wherein the virgin resin is selected from HOPE, LLDPE, LDPE, or combinations thereof.

An object of the present invention is to provide a composition capable of allowing for production of a crosslinked foamed product suitable for applications of footwear parts such as soles and excellent in properties such as lightweight properties, heat shrinkability, compression set and mechanical strength in a well-balanced manner, a foamed product using the composition and a footwear part using the same. An ethylene copolymer composition including an ethylene copolymer (A) satisfying all the following requirements (A-a), (A-b), (A-c) and (A-d), ethylene/α-olefin having 3 to 20 carbon atoms/non-conjugated polyene copolymer rubber (B), and, if necessary, an ethylene/polar monomer copolymer (C); (A-a) a vinyl group content per 1,000 carbon atoms is 0.025 to 0.3, (A-b) MFR.sub.10/MFR.sub.2.16 is 7 to 20, (A-c) a density is 0.850 to 0.910 g/cm.sup.3, and (A-d) a melt flow rate is 0.01 to 200 g/10 min.

a film composite for manufacturing a package for planar carriers of pharmaceutical active substances, for example transdermal patches, encompassing, in a direction from the outer side of the film composite toward its inner side: a metal layer; an acrylic-acid-containing joining layer; a polyethylene layer; and a COC layer made of cycloolefin copolymer, a side of the COC layer which faces away from the metal layer being an exposed surface of the film composite, wherein provision is made that the polyethylene layer encompasses metallocene polyethylene.
