| titleOfInvention | Production process of vacuum bag film, vacuum bag film and water-locking vacuum bag |
| abstract | The invention discloses a production process of a vacuum bag film, which comprises the following steps: s1: preheating and softening the film; s2: the roller and the rubber roller form a pair roller for rolling the softened film obtained in the S1, wherein the surface of the roller is provided with a point-shaped bulge, the roller rolls the first surface of the film to form a water locking recess and a convex ring of the first surface, and the convex ring is positioned at the outer edge of an opening of the water locking recess; s3: cooling the film; the preheating temperature of S1 is not less than the softening temperature of the film. The production process of the vacuum bag film comprises the steps of preheating and softening a film, rolling and softening the film by a pair roller consisting of a roller surface provided with point-shaped bulges and a rubber roller to obtain a first surface with a water locking recess and a convex ring positioned at the outer edge of an opening of the water locking recess; the first surface of the obtained vacuum bag film is provided with the punctiform water locking depressions and the convex rings, so that excessive water in the vacuum bag is effectively prevented from being pumped out when the vacuum bag is vacuumized, and more water is stored in the vacuum bag. The invention also discloses a vacuum bag film rolled by the method and a water-locking vacuum bag prepared from the vacuum bag film. |
