The use of vacuum bag and the method of controlling its thickness

source:Industry News release time:2022-09-28 Hits:    

  

  Vacuum bags are widely used in various industries:

  1. Food packaging: rice, meat products, dried fish, aquatic products, bacon, roast duck, roast chicken, roast pig, frozen food, ham, bacon products, sausages, cooked meat products, pickles, bean paste, condiments, etc.

  2. Hardware electronics: suitable for packaging of circuit boards, electronic products, mechanical accessories, consumer goods, industrial products, etc.

  3. Pharmaceutical packaging: vacuum bags are suitable for packaging large-scale machinery and equipment, chemical raw materials, pharmaceuticals, etc.

  How to control the thickness of the vacuum bag:

  1. The key to the vacuum bag's thin and thick symmetry is the thickness and symmetry of the film in front of the composite. That is to say, the reason why it is light and thin is the premise to improve its quality.

  2. The high barrier property of vacuum bag plastic film is closely related to the thickness of its plastic film.

  3. The uniformity of the thickness of the plastic film of the vacuum bag endangers the drawing characteristics of the plastic film machinery and equipment. The aluminum foil bag plastic film with good thickness uniformity can obtain good packaging printing accuracy and composite quality.

  4. For the same inner material, the larger the vacuum bag film thickness, the higher the start-stop heat-sealing temperature, and vice versa. That is to say, the thickness of the vacuum bag film is uniform, which can obtain uniform pinning quality and prevent some hidden dangers of heat sealing.

  It can be found from the above introduction that the vacuum bag is mainly a bag formed by a combination of various plastic films through a bag making machine. For example, the vacuum bags currently on the market are mainly designed with a four-layer structure and have a good water and oxygen separation function. In addition, for vacuum products with qualified quality, they must be tested according to GB and ASTM standards in the production process, and meet the national environmental protection testing requirements. If the company does not know how to conduct the test, it can directly provide a third-party test report to the testing technician. For products that need to be exported, they should also meet the strict environmental protection standards for packaging materials in the European Union and North America.

  In addition, some vacuum bags are made of plastic particles. Such granular plastic materials can be divided into three types: ordinary plastics, engineering plastics and special plastics. Its properties are opaque, silver-white, anti-gloss, good barrier, heat-sealing, shading, high and low temperature resistance, oil resistance, fragrance retention, softness, etc. Due to its low price and durability, so It is also more common in the market.
