Abstract

PURPOSE:To obtain a tape for a first aid strap with excellent fitness by drilling a tiny hole in a film with a specified thickness molded by a specified ethylene/ acrylate lower alkyl ester copolymer, a specified linear polyethylene and a specified resin composition. CONSTITUTION:Numerous tiny holes 2 are drilled into a film 1 with a thickness of 30-120mum molded by 40-70wt.% of a copolymer of ethylene and a lower alkyl ester of acrylic acid with a content of the lower alkyl ester of 10-30wt.%, 20-45wt.% of linear polyethylene with a melt flow rate of 0.3-2.5g/10min. and a density of 0.880-0.950g/cm<3> and a resin composition containing 10-40wt.% of a thermoplastic elastomer to make a tape 7 for a first aid strap. The tape 7 for strap is a film excellent in elasticity and resistance to tearing and thus, there is no breakage from the tiny holes 2 drilled with a better adhesion to a self-adhesive.

However, since the soft vinyl chloride resin contains a large amount of a plasticizer, the plasticizer has an adverse effect on the body's health and the generation of toxic chlorine gas when incinerated. In view of environmental protection such as generation of dioxin when landfilled, it is proposed to replace the sheet with a polyolefin resin such as polyethylene or polypropylene.

Polyolefin resins are excellent in hygiene and environmental protection, but they are non-polar resins and therefore have poor adhesion with pressure-sensitive adhesives. Since it is a crystalline resin, there is a problem that it breaks from the small holes that have been drilled. An object of the present invention is to provide a tape for plasters made of a polyolefin resin, which satisfies the requirements (1) to (3).
