One of the most important stages that we deal with in the production and supply of various products is their packaging stage, which should be done with great attention. Various methods and equipment are used for packaging small and large products, which we can choose the appropriate packaging according to the type of product, product weight and product dimensions. Among the most common and best packaging equipment are stretch films and shrink, which have very high resistance and can protect products well.
But maybe this question will arise for all of you, when to buy stretch film or nylon shrink, can we use them for a long time? Do stretching and shrink films have an expiration date? These products have an expiration date just like other products we use in our daily life. In this case, many users have a question as to why stretch films or shrink expire prematurely!
In this article, we are going to tell you about the expiration date and all the things about stretch film or shrink; let’s explain Stay with us.
In total, you can use your shrink and stretch nylon for one year. However, there is no obstacle to use these plastic covers after one year. But if a long period of time has passed since the production date of these products, the pressed parts in the shrink will start to open and the stretch films will also lose their elasticity and even change their color. If the stretch film changes color from transparent white to yellow after some time, we can say that the expiration date of the packaging of this product has arrived and we should discard them.
Various factors cause failure in shrink and stretch films, which also causes expiration. Sometimes, by paying attention to these small points, we can increase the life of these products several times and avoid additional costs for ourselves. In the following, we examine the most important factors that lead to the deterioration and expiration of stretch films and shrink .
One of the most important factors influencing the premature expiration and deterioration of any type of plastic is extreme heat or cold. High and long-term and intense heat can cause shrinking and shrinking of stretch film and shrink and take them out of their standard state. In this case, the use of this coating in packaging products is not optimal and the films are constantly torn. On the other hand, the packaging may stick to the products and cause damage to them. Exposing shrink or stretch film to very cold weather for a long time will cause product coatings to crack and dry.
Other environmental factors that can advance the expiration date of the plastic covers of your products are dust and dirt. When there is a lot of dust on the packaging of the products, the stretch film or shrink lose the ability to stick and hold the products tightly, and as a result, they cannot guarantee its security. The humid environment can also have such an effect on the structure of the packaging shrink. Therefore, be sure to check the storage conditions of these products and put them in a suitable temperature and dry place to avoid such problems.
The duration of time is also influential in the deterioration of stretch film and shrink, and it is one of the important factors for the expiration of stretch film. Not using stretch films and shrink, makes these products exposed to various factors such as heat and cold, dust and weather conditions, which we have already explained the damage caused by them.
Before preparing any plastic cover for product packaging, first learn how to maintain them and prepare the necessary equipment. Having a large number of any type of stretch film and shrink and using them after they expire will cause many problems in the packaging process and even after that. Stretch films and shrink nylons should be stored in an environment with a temperature of 0 to 25 degrees Celsius; that you friends should also observe this point.
In the winter and summer seasons when the air temperature is cold or hot more than usual, in order to maintain your packages correctly, you should control the air temperature by means of heating or cooling equipment. Of course, for nylon stretchers, we must keep them in a sanitary environment, which is very important, and we must pay special attention.
If the place you want to store is exposed to extreme heat in the summer season, it is better to use suitable cooling equipment such as special coolers to prevent any problems with shrink and stretch films. If the coatings are kept at a temperature higher than 35°C for a long time, they will expire and will no longer be usable.
In hot situations of the year, place your shrink and stretch film in a cool area, but do not adjust the ambient temperature so that they suffer from exposure to cold weather. Places that are closer to the ground and away from sunlight, such as the basement of a workshop, house or factory, are suitable environments for storing packages.
As we mentioned earlier, the exposure of stretch films and shrink to very cold weather and for a long time can make the cover of the packages fragile. PVC stretch films can break just like a glass if placed in a cold environment. During the cold and stormy times of the year, keep the product packages away from the ground and cold environments, and make sure that moisture and water do not enter the product packaging storage area.
Proper storage at all times and being aware of the expiring factors of stretch film and shrink can help us to use these packages more optimally. In general, we can say that by keeping these plastic covers away from any excessive cold, heat and dust and not storing the packages, we can use these products for a longer period of time. I hope this article was useful and effective for you.
