Abstract

PURPOSE:To obtain a sterilized package which is easily unsealable and not to deteriorate the air-permeability of air-permeable base member, by forming an adhesive layer at the lower temperature than the lowest temperature for making a film, applying a particular water soluble and easily unsealable adhesive to make a layer. CONSTITUTION:In a sterilizing packed material, in which synthetic resin film member is used for one of packing materials and an air-permeable member comprising non- woven cloth of synthetic resin and a paper base member, etc., are used for the other of packing materials and the both members adhere with heat to each other at the necessary parts. A water soluble and easily unsealed adhesive, in which 100-1000 parts of low molecular weight polyethylene and 150-500 parts of fine particle heat- adhesive of polyethylene against 100 parts of easily unsealable adhesive in weight respectively for whole surface of the air-permable base material, is applied to make a layer and to form an adhesive layer at the lower temperature than the lowest temperature for making film. The easily unsealed adhesive is a water soluble dispersion type which is variously processed for denatured treatment of ethylene or ethylene-vinyl acetate copolymerization, etc., as main components. This water dispersive and easily unseating adhesive is preferably applied by the volume of 5-15g/m<2>.

(Prior Art) Easy-to-open sterilization bags using an air-permeable base material made of a synthetic resin non-woven fabric have been known for a long time, and the manufacturing method for these bags is to use a solvent-based easy-to-open bag on the above-mentioned synthetic resin non-woven fabric. However, in this method, the adhesive seeps into the breathable base material and causes a decrease in air permeability. This method has the disadvantage that it is necessary to apply an anchoring agent layer to the adhesive base material, or to apply the adhesive in a grid or dotted manner.

If this is applied to 100 parts by weight of the easy-open adhesive, easy-opening will not occur if the weight is 100 parts by weight or more, and if more than 1,000 parts by weight is used, the adhesion will become weak and the coating film will tend to be repelled. arise. Ethylene-based fine particulate thermal adhesive is a mixture of modified ethylene-vinyl acetate copolymer, modified ethylene-macrylic acid ester copolymer, chlorinated polypropylene, etc., and the blending amount is 50 parts by weight or less. If the amount is more than 500 parts by weight, the adhesion becomes too strong and easy opening cannot be obtained.
