Industry standard for container bags
Structural technical requirements
1, the waist band strength should reach more than twice the strength of the substrate.
2. The waist band must be sewn on the outside of the sling to enhance the bearing strength of the sling.
3. The bag body with side seam must be sewn under any sling to enhance the edge seam strength.
Sewing technical requirements
1. The tensile strength of the side seam must reach more than 67% of the strength of the substrate.
2, the tensile strength of the bottom seam must reach more than 42% of the strength of the substrate.
3, sewing requirements flat and straight, no needle off broken thread, no floating thread, needle, needle back and down needle not less than three needles, sling length to be equal, lap seam to be uniform and straight.
4, container bag requirements flat and straight, no obvious lack of less dimension, no obvious defects, the surface is not allowed to have obvious stains, the bag body printing pattern is clear, accurate position.
Container bags are gradually developing in the direction of environmental protection
Container bags have become more and more inseparable from our lives, and our work has also been closely related. And it is such a development trend and social status, then the problems existing in his body will gradually be amplified and people's attention.
Since China entered the environmental awareness in 2008, the environmental problems of container bags have been put on the agenda, and the widespread use of plastic bags made of recycled materials was ordered to stop production, replaced by container bags and non-woven bags to become the world of packaging. At present, under the requirements of the government and people, sustainable environmental protection ingredients have gradually entered our lives. Now from the point of view of sustainable development, plastic bags are difficult to define, it is almost does not meet the requirements. We need to reform it accordingly.
In the future development process, container bags gradually develop in the direction of environmental protection and enter a state that can be reused. In the future, the container bags used in packaging can be reused, and it can also be freely decomposed. It can be decomposed naturally under the sunlight, without causing pollution to our environment. This will achieve the environmental protection effect of our plastic bags in the future.
Pressure and drop test of container bags
Before we use the container bag, in order to be safe, we must ensure that its quality is qualified and its performance meets the requirements. Below we will take a look at its pressure and drop test methods.
In the pressure test, it is necessary to put the full load container bag on the pressure machine for pressure test, the pressure added by the pressure machine is four times the full weight of the container bag, or the static load method, that is, the dead weight of the four layers of full load bag, the pressure time is more than eight hours, if the contents do not overflow and the bag body is not damaged, it means that the container bag has passed the test. During the drop test, the full load container bag is lifted with lifting equipment, the bottom of the bag is above 0.8m from the ground, and then vertically falls to the hard and flat ground at one time, if the contents are not spilled and the container body is not damaged, it means that the test is passed.
When filling, the container bag mouth is aligned with the filling funnel mouth and tied tightly to prevent dust or particles from leaking out. The container bags are usually lifted to fill and placed on a tray below to be filled and pulled away.
How to help the development of container bags
Container bags are currently an important tool for loading and unloading large goods, and their role is self-evident, but if two aspects of the problem are improved, it will help the development of container bags:
1, from the perspective of container bag manufacturers, the urgent need to improve the place is its production of energy saving and consumption reduction, related to the overall cost of the product and the market competitiveness of the size of the problem. From the perspective of production equipment, it is necessary to introduce more energy-saving and environmentally friendly equipment to ensure energy saving and power saving, which is the focus.
2, from the point of view of market use, such as falling in the lifting process, easy to scratch in use and other problems are exposed, the use of more capricious material and workmanship is needed to solve. Container bag manufacturers should pay attention to the details in the production process, any part of the problem will directly affect the quality of the final container bags, so pay attention to the quality of strict control, so as to ensure the long-term development of container bags.
