包装袋
Document Type and Number:
Japanese Patent JP7383221
Kind Code:
B2
Abstract:
To obtain a packaging bag which suppresses an adsorption amount without the reduction in the non-adsorption performance even when there is a large non-application part considering a deviation between a coating region and a sealing region in application of a coating agent for non-adsorption layer formation.SOLUTION: In a packaging bag (1) having a sealant layer (21) applied with a coating agent (3) for non-adsorption layer formation suppressing adsorption of contents to the packaging bag on the innermost layer, the coating agent application for non-adsorption layer formation of the sealant layer has a solid coating region (31) that is applied in a solid manner and a non-coating region (32). The space between the solid coating region and the non-coating region is separated by a pattern buffer region (33) formed by partially pattern-coating the coating for non-adsorption layer formation. The pattern of the pattern buffer region is the region that is coated so as to achieve the application area ratio of 40-60%.SELECTED DRAWING: Figure 1
