5230 results about "Vacuum packing" patented technology

Vacuum packing is a method of packaging that removes air from the package prior to sealing. This method involves (manually or automatically) placing items in a plastic film package, removing air from inside, and sealing the package. Shrink film is sometimes used to have a tight fit to the contents. The intent of vacuum packing is usually to remove oxygen from the container to extend the shelf life of foods and, with flexible package forms, to reduce the volume of the contents and package.

Composition of air-permeable film with low permeation volume and preparation method thereof

The invention discloses a composition of an air-permeable film with a low permeation volume. The composition consists of the following components in percentage by weight: 30-60 percent of polyolefin resin mixture, 5-15 percent of permeation volume regulator, 30-55 percent of surface-modified nano-grade organic particles, 0.2-0.5 percent of antioxidant, 0.1-2.0 percent of lubricant and 1-3 percent of coupling agent. A preparation method of the composition comprises the following steps of: mixing a micro-grade inorganic filler with the coupling agent in a high-speed mixer to obtain a pretreated filler; feeding the pretreated filler, polyolefin resin, a modifier, the antioxidant and the lubricant into a double screw extruder by using a feeding system, extruding, cooling, pelletizing, drying, and packaging with an aluminum film bag in vacuum to obtain a finished air-permeable film composition with low permeation volume; and casting the prepared composite by using an extruder with a T-shaped film head, and stretching with a single shaft in two steps, wherein the stretching rate is 0.5-3.5. The invention has the advantages: 1, the nano inorganic filler is added, so that the mechanical property of the air-permeable film can be enhanced; 2, the surface of the inorganic particles is coupled, so that the compatibility with the polyolefin resin can be enhanced; 3, due to the adoption of the T-shaped film head, the drawing efficiency and the flatness can be fully enhanced; and 4, due to the adoption of the permeation volume regulator, the permeation volume of the air-permeable film can be lowered remarkably.
