What is a heat seal bag? How to use heat seal bag

Heat seal bag is a special packaging material, it can effectively prevent food, drink and other contact with the moisture in the air. When we need to save some liquid, heat sealing bags are also good for us to do the job.

1: Definition of heat sealing bag

Heat sealing bag is a special packing material that can protect items from moisture during transportation. The material is commonly used in a variety of packaging industries, including food, pharmaceuticals and cosmetics. The heat sealing bag is generally made of two layers of film, the upper layer is the coating material, the lower layer is the filler, the coating material is printed with product information or instructions, the film is heated to melt, the middle layer of the film into the outer coating material, forming a layer of sealing film. This is custom plastic seal bags.The material has good heat insulation and insulation properties, so it can effectively prevent heat loss; At the same time, because of its double-layer structure, so the heat conduction ability is strong, not easy to be affected by the wet environment and metamorphism.

2: The role of heat sealing bag

The function of heat sealing bag is mainly to protect the product from the influence of external environmental factors. High temperature will lead to expansion of goods, resulting in deformation or damage to packaging; Low temperature weather can avoid water loss caused by high external temperature, so it can play a certain moisture-proof effect. In addition, because products produced under extreme conditions such as high temperature, high pressure and strong light are prone to oxidation, the use of insulation materials can also effectively prevent product deterioration. Usage :1. Put the heat sealing pocket into the box and fix it with tape outside; 2. Check whether there is air leakage every time you open or close the heat seal bag; 3. In case of emergency, such as damaged goods or oil leakage, new heat sealing bags should be replaced in time; 4. If there is no goods in the heat sealing bag, it is suggested to throw it away as soon as possible;

3: Use method

Heat seal bag is a special packaging material, it can prevent the product from getting damp and avoid environmental pollution. When using heat seal bags, pay attention to the following: 1. Choose the right plastic bag: Heat seal bags are usually made of non-toxic, non-perishable plastic, so avoid using bags that are easily damaged or smelly. 2. Properly install the heat seal bag: After placing the plastic bag in the heater, ensure that it is completely cooled. If you find the heat seal bag broken, do not continue to use it. 3. Check heat sealing bag regularly: In order to maintain product quality, please check and maintain it before each use. 4. Safe storage: When the temperature exceeds 30.9, you should seal the heat sealing bag to avoid damage.

If you want to use a heat seal bag for storage, pay attention to temperature and humidity. Generally, sealing at 0 degrees Celsius for more than 3 hours is sufficient. But if we want to preserve a product, like ice cream, for a long time, we need to make sure that the ingredients are completely oxidized and can’t absorb any water.
