It is becoming a consensus to reduce Multiple packaging of food, which will avoid excessive waste of resources. And reducing the secondary packaging of plastic bags for food will reduce irreversible damage to the environment. Because plastic packaging will exist in the environment for a long time and is not biodegradable. Paper tube food packaging is becoming more popular due to its biodegradable properties. In addition to candies and chocolates, Strawberry dried fruit is also packaged in food tubes.
Put the Strawberry dried fruit directly into the cylindrical packaging, and the airtightness and dryness of the packaging must be fully considered. For this reason, using food-grade tin foil as the inner liner of the paper tube can maintain the dryness inside the round boxes and effectively extend the shelf life of dried fruits. The tightness of the lid part is also very important. The bottom of the food tube packaging is sealed with an iron cover, and the top is an easy-to-tear foil cover, which is 100% sealed. The easy-to-tear foil cover is very easy to open, which enhances the product experience. Since the foil cover is relatively thin and is a disposable product, it can no longer be sealed to the food tube after use. Therefore, the use of a plastic cover in addition to the foil cover will play a supplementary role and can seal the opened food tube many times.
