Stretch Bag/inner Bag

Container bag manufacturers in the production, in order to be able to have better performance before being put into use, usually have to first carry out a pressure test, only through the pressure test of the container bag is the quality of qualified container bags. So do you know how to carry out the pressure test of container bags? In fact, speaking of the pressure test method of container bags can be said to be very simple and rough, since it is a pressure test, of course, it is necessary to install something to test, and the specific operation method will be introduced in the following.
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.
In the container bag pressure test is often carried out in accordance with the above method, so the test out of the container bag is also very convincing, on the production of pressure bags our company's experience is very rich, and for some other related knowledge of the container bag we understand is also a lot. So if you want to know more about container bags through us, you can contact us to get some relevant understanding, I believe you will have something to gain.

The use of packaging bags is now very common, and there are various types of packaging bags on the market today, which also meet the different needs of people in different occasions. Packaging bags are very common in people's lives, and it can be seen that its role is large and its use is widespread. Ton bags are often used in transportation, usually see the transport of different items also have different uses, in the usual use of everyone should know more about ton bags, now we take a look at the benefits of container bag packaging.
What are the benefits of container bag packaging
1, occupy less space. The empty bag is foldable, small in size, and the full bag has a large capacity, saving space than the small bag packaging.
2, can be used to maintain the product. The ton bag has the function of rainproof and impervious, and it can also be moisture-proof after being filled and placed outdoors.
3. Deliver bento. There is a special lifting ring on the container bag, which is easy to lift, load and unload the lifting equipment.
4, packaging restrictions. As long as it is powder and granular products, container bags can be packed.
5, long life, can be used repeatedly. Container bags are made of high strength materials, durable and acceptable for reuse.
6, can greatly advance loading and unloading power. It has large capacity, fast loading and unloading, and more than ten times the working efficiency of conventional paper bag packaging.

Although the container bag manufacturers can ensure that the packaged goods in the loading and unloading, transportation and storage process intact. But the precondition is that the quality of the ton bag is qualified. So, what performance do qualified container bags need to have? The following container bag manufacturers will introduce you.
1, mainly refers to the strength of the ton bag. In the design, we should consider the packaging volume, the weight of the load and the packaging unit (number), but also consider the distance of transportation and the number of handling times, which means of transport and transportation methods.
2, storage, should be based on the user's conditions of use reasonable selection of materials, reasonable process ratio. For example, the anti-aging ability of plastic materials under sun exposure is a main indicator to determine the quality of tons of bags, and it is also a problem often encountered in the actual use of tons of bags, so attention should be paid to the use of anti-ultraviolet agents and the selection of anti-ultraviolet radiation materials in the production process.
3, usability, to fully consider the specific ways and methods of customers using tons of bags, such as lifting, transportation and the performance of the loaded materials. In addition, it is also necessary to consider whether the goods are food, to ensure that there is no adverse effect on the food.
4, sealing, packaging materials are different, sealing requirements are different, such as powder or toxic items, afraid of contaminated items on the sealing performance requirements are very strict; Special materials that are prone to moisture or mildew also have special requirements for air tightness, so when designing ton bags, pay attention to the impact of the substrate film process and sewing process on the sealing.
