PROBLEM TO BE SOLVED: To provide a food packaging method which can prevent the intrusion of foreign materials, has easily openable properties, and does not deteriorate the convenience that a packaging bag can be opened/closed repeatedly by a binding tool, etc., a laminated film for an easily openable food packaging bag, and a bag for easily openable food packaging. SOLUTION: The food packaging method in which the laminated film (I) having a surface layer (A) of a propylene resin and a heat seal layer (B) containing a 1-butene 1 copolymer is used, under conditions in which adhesion strength is 7.5-30 N/15 mm, after food is packed in the bag for food packaging having an opening part which is made by melt-adhesion, or after the bag for food packaging having the opening part is made by packing the food while being melt-bonded, easily openable packaging is made by heat sealing under conditions in which the opening part of the bag has strength of 0.1-5 N/15 mm, the laminated film for the easily openable food packaging bag which has the layers (A) and (B), and the bag for easily openable food packaging which is made by melt-bonding the laminated film are provided. |
