▎ 摘 要
NOVELTY - Vacuum bag film comprises 95-99 pts. wt. nylon (1), 1-5 pts. wt. nanosheet material (2) and 0.5-1 pts. wt. lubricant. USE - Vacuum bag film used in packaging (claimed). ADVANTAGE - The vacuum bag film has high barrier property, mechanical property, good research significance, and it improves the tightness of the nylon to greatly enhance the barrier property of the vacuum bag film, radically solves the problem that the nylon molecular cross-linking structure is damaged in the high-humidity environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing vacuum bag film, involves: (A) mixing and granulating nylon, nanosheet materials and a lubricant to obtain modified nylon particles; and (B) mixing and blow-molding the modified nylon particles obtained, and adding heat stabilizer and optional antistatic agent to obtain vacuum bag film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of internal microscopic simulation structure of vacuum bag film Nylon (1) Nanosheet material (2)
