PROBLEM TO BE SOLVED: To provide a tray shrink package using a shrink film, particularly, a shrink package which is easily openable even when it is a gas-substituted shrink package using a high strength gas barrier film. SOLUTION: In a pillow type shrink package, an easily openable shrink package which can be easily opened from any parts of front and back seal parts, is obtained by comb-likely providing I-type notches which make seal outside edges as starting points over the whole width of the front and back seal parts toward the inside of the package on at least one of the front and back seal parts.
