<\/a><\/p>\nIntroduction to vacuum packaging<\/strong><\/h2>\nVacuum means vacuum and is said to be a space that is empty of matter. Therefore, in general, any package in which the air inside is evacuated using various devices or air suction valve is called vacuum.<\/div>\n<\/div>\nThe main purpose of vacuum packaging is to reduce the amount of oxygen in the packaging. This work reduces the growth rate of aerobic bacteria and also reduces oxidation reactions, and in this way, the shelf life of products, especially food, will increase for a long time. With this method, the quality of fresh food products is maintained without thermal, chemical or refrigeration treatment that is used in the production of canned goods, frozen packages, dried, etc.<\/div>\n<\/div>\nIn this type of packaging for delicate and fragile food products such as potato chips that may be crushed by the vacuum process, inert gases such as nitrogen are injected into the package and replaced with oxygen. In cases such as red meat packaging, they use carbon monoxide instead of oxygen to preserve the red color of the meat in the packaging.<\/div>\n![\"Vacuum](\"https:\/\/www.vazinplast.com\/wp-content\/uploads\/2021\/09\/\u067e\u0644\u0627\u0633\u062a\u06cc\u06a9-\u0648\u06a9\u06cc\u0648\u0645-2-300x300.jpg\")
<\/a><\/p>\nAdvantages of vacuum plastic packaging<\/strong><\/h2>\nAs we said, vacuum plastic packaging is widely used in the food industry and its advantages include:<\/p>\n
\n- Increased shelf life:<\/strong> Studies have shown that vacuum packaging can increase product shelf life by 50%. It is interesting to know that vacuumed food can last two to three years in the freezer and up to two weeks in the refrigerator.<\/li>\n
- Savings:<\/strong> The ability to store food for longer allows us to reduce food spoilage and waste. Also, this technology allows food manufacturers to buy ingredients in bulk at a lower price and store them efficiently.<\/li>\n
- Preservation of taste and quality:<\/strong> Since food is packed in the absence of air, its moisture, texture and taste are preserved. The nutritional value of the food also remains intact.<\/li>\n
- No need for preservatives:<\/strong> Many traditional methods of food storage require chemicals and preservatives. Unlike them, vacuum packaging does not include the use of any harmful external elements.<\/li>\n<\/ul>\n

<\/a><\/p>\nThe vacuum envelope is sewn on three sides<\/strong><\/h2>\nIn most cases, vacuum plastic is produced in the form of a bag. The most ordered type of vacuum envelope is the three-sided sewing envelope. These envelopes are used for packaging food products and protein products such as fish and shrimp, sausages and sausages, cosmetic products such as bleaching powder and liquid, hair color and other products such as vegetables and vegetables, plums and lavash, seeds, poisons and any product. Others that need to be vacuumed are usable. Three-sided sewing vacuum envelopes are produced in two types of metallized, two transparent sides, as well as one metallized side and one transparent side, and they can be presented in different colors.<\/p>\n

<\/a><\/p>\nHow to store vacuum film<\/strong><\/h2>\nDue to the fact that vacuum plastic is a very sensitive material and easily changes its shape, special points should be paid attention to in its maintenance, which we will state below:<\/p>\n
\n- Note: Never stack vacuum plastic rolls and never buy more than you need. These nylons lose their properties after being unused for a long time.<\/li>\n
- Do not compress the rolls in any way or stack them vertically in any way. This will cause the rolls to slide and become conical.<\/li>\n
- Note that never expose the rolls to moisture as they are extremely vulnerable.<\/li>\n
- These nylons are vulnerable to sunlight, so keep them out of the sun.<\/li>\n<\/ul>\n
