  With the improvement of modern living standards and the quickening pace of life, people are demanding more and more for the safety and convenience of food.Businesses to have good products and exquisite packaging can often seize the hearts of consumers.There are many kinds of outer packaging. Win-win PACK mainly provides customers with follow-up packaging equipment for products. For example, POF film thermal shrinkable machine is specially designed for products requiring thermal shrinkable packaging.It is to wrap the film on the outside of the product and use the principle of film thermal shrinkage to pack the product.

 Can the POF film shrink machine extend the shelf life of food after packaging?This must be a concern to all of us.In this way, we have to know under what conditions the food can achieve the desired long-term preservation and no deterioration, which is mainly caused by the reproduction of microorganisms.Another is the oxygen in the air caused by oxidation deterioration;Enzymes in food promote food metabolism, producing heat, water vapor, and carbon dioxide, which can lead to spoilage.Low temperatures slow down microbial activity and chemical reactions in the food itself, and the seal prevents oxidation of the air, so it doesn't spoil for a long time.From this point of view, in order to preserve food for a long time, the vacuum packaging is needed to achieve the food does not contact oxygen.POF film thermal shrinkable machine thermal shrinkable package just wraps the product without vacuuming, but it separates the product from oxygen when it shrinks, just without vacuuming.So we can not be sure that the use of POF film thermal shrinking machine packaging can extend the shelf life of food, but it will be much better than the ordinary packaging.

   POF film shrink machine in the packaging industry market has been in change, progress and competition.WIN-WIN PACK's POF film thermal shrinkable machine always grasp the humanization, from the customer's point of view, the continuous pursuit of quality improvement and constantly strict requirements on themselves and break through their own, so that consumers have the ability to feel and use the POF film thermal shrinkable machine packaging products brought by the charm, feel the magic of science and technology.
