Food Grade PE Square Valve Bag

Food-grade PE square valve bags are square valve-type packaging bags made of polyethylene materials that meet food contact standards. They have a unique square structure. This structure allows them to stand firmly on flat surfaces. It makes stacking and storage much more convenient. The valve design is a major feature of these bags. When filling materials, it is particularly convenient. Moreover, the sealing effect is also very good. The materials used to make these bags have undergone strict testing. They are ensured to be non-toxic and harmless. They can directly come into contact with food-related materials. During the production process, strict compliance with food packaging safety regulations is also maintained.​

Its advantages are prominent. First of all, there is a guarantee in terms of safety. The materials meet food-grade standards. They will not contaminate the packaged food. They can keep the food safe. Secondly, the sealing performance is excellent. The valve design can effectively block air and moisture. It keeps the materials inside the bag dry. This extends the shelf life. Furthermore, the square structure makes stacking very stable. It saves storage and transportation space. The handling efficiency is also improved. In addition, filling is very convenient. The valve design makes the material filling process smoother. It reduces the occurrence of spills and leaks. Moreover, it has good toughness. It is not easy to break. It can protect the materials inside during transportation and storage. At the same time, the cost is relatively affordable. It is suitable for batch use by food enterprises.​

In the food additive industry, they are often used to package various powdery or granular food additives. Such as flavor enhancers, preservatives, and the like. They can ensure the purity and stability of the additives. In the grain processing industry, products like flour, starch, and grain flour. They are often packaged with these bags. It is convenient for storage and transportation. It can also prevent moisture and insects. In the sugar product industry, white sugar, rock sugar powder, etc. They are also packaged with these bags. The good sealing performance can prevent moisture absorption and caking. In the dairy industry, some powdered dairy products such as milk powder and whey powder. They are also suitable for packaging with these bags. It ensures product quality.​

The size can be customized according to the amount of materials. It can be as small as a few kilograms of packaging. Or as large as dozens of kilograms in specification. All needs can be met. There are many color options. Transparent color can be used, which is convenient for checking the materials inside. Colors can also be chosen according to brand needs. Light-shielding materials can also be added to avoid the impact of light on the materials. The printed content is flexible. It can include product names, ingredients, production dates, shelf lives, manufacturers, and other information. It clearly displays product details. The thickness can be adjusted. According to the weight and characteristics of the materials, a suitable thickness is selected. This ensures the load-bearing and protective performance of the bag. In addition, the size and style of the valve can also be customized. It is adapted to different filling equipment.​

The material properties of food-grade PE square valve bags are very suitable for food packaging needs. They have good chemical stability. They will not have chemical reactions with food materials. They can maintain the original quality of the materials. The low-temperature resistance is also good. In low-temperature environments, they will not become brittle and crack. They are suitable for packaging materials that need to be stored in cold storage. The material is soft in texture. It has good impact resistance. When subjected to collisions, it is not easy to break. Moreover, it has a certain degree of oil resistance. When packaging oil-containing food materials, there will be no leakage. At the same time, the materials meet environmental protection requirements. Some products can be recycled.​

When using them, some details need to be paid attention to. When filling materials, do not exceed the maximum load capacity of the bag. Otherwise, the bag may break. When storing, they should be placed in a dry and ventilated place. Avoid direct sunlight and high-temperature environments. Prevent material aging. During handling, avoid sharp objects from the bag. This prevents material leakage. If Food grade PE Square Valve Bag is found to be damaged or the valve is not tightly sealed. It should be replaced in time. Prevent materials from being contaminated.
