PACKING MATERIAL, METHOD OF AND DEVICE FOR ITS PRODUCTION |
摘要 |
FIELD: mechanical engineering; packing materials for packing containers featuring high gas barrier properties. SUBSTANCE: material has laminated structure with outer and inner layers, at least one of which is made of polyolefin. Backing and fat resistant paper layer is placed between outer and inner layers. Fat resistance to TAPPI of fat resistant layer is within 100 and 400 s. At least one of surfaces of fat resistant layer is activated by surface treatment and is coated with polymer to form surface layer. Gas barrier characteristic of packing material is increased by combination of fat resistant layer and polymeric layer in laminated structure. EFFECT: enhanced quality of packing material. 17 cl, 5 dwge
