The design and production of food ton bags must ensure that they are non-toxic and harmless, and pass the food-grade safety certification of packaged food. The anti-aging ability of food ton bags in the sun is relatively poor, so we must pay attention to strengthening the sun protection function during the production process
Food ton bag
Main points of design for ton bag manufacturers
We all know that the design requirements of food bags are very important, because the safety of food is closely related to the safety of our bodies. Therefore, we must strictly demand its design.
The design and production of ton bag manufacturers must ensure that they are non-toxic and harmless, and pass the food-grade safety certification of packaged food. The anti-aging ability of food ton bags in the sun is relatively poor, so we must pay attention to strengthening the sun protection function during the production process.
In addition, the design of food tote bags also needs to pay attention to the following:
1. Determine the weight of the loaded goods, and determine the volume of the food grade ton bag according to the proportion of packaging materials. It also depends on whether the loaded material is sharp and hard block material. For example, when designing food grade tonnage bags, the base fabric should be thicker, but it can also be thinner.
2. When designing the structure of food-grade tonnage bags, the standard stipulates that the strength of the waist cuff should be more than twice the strength of the base fabric, but the actual design effect is not good, because the strength of the base fabric and the waist cuff is inconsistent. Cause the base cloth to crack first. In the design, the waist hoop and the base fabric use the same strength of the base fabric material to avoid this problem.
3. In the design of food grade ton bags, the selection of sling material is very important. Now there are standards on the market for food ton bags that clearly define a safety factor of 1:6. In the actual design of food grade ton bags, one must consider the loss of sling strength during the sewing process; the other must consider the lifting method. When a sling is additionally provided for a food-grade ton bag, two rings and four rings can be used to increase its tensile strength.
