The accordion bag is a kind of packaging bag with folding and unfolding characteristics. It can adjust the size according to needs and adapt to items of different sizes. With good plasticity and extensibility, the accordion bag can be easily expanded when in use and folded into a smaller size when not in use to save storage space.
Because of its excellent performance, accordion bags are widely used in various packaging scenarios, especially for packaging and transporting items with variable volumes. For example, items such as clothes, shoes, bedding, stuffed toys, books, etc., because they come in different sizes and shapes, require an adjustable packaging bag to accommodate them. In addition, accordion bags can also be used for food packaging, postal packages, express packages, and other packaging needs that need to be flexibly adapted to the size of items.
However, during the use of accordion bags, the problem of easy bag breakage is more prominent. How should it be solved?
The main reasons why organ packaging bags are easy to break are as follows:
Material selection: Organ packaging bags are usually made of film materials, such as polyethylene (PE) or polypropylene (PP). These materials are relatively weak and prone to tearing or punctures.
Stress problem: There is a stepped position at the intersection between the organ position and the horizontal sealing position. That is, there are only two layers of material heat sealing on both sides of the organ at the horizontal sealing position, while the horizontal sealing edges of the organ position will have four layers of film that need to be heat sealed. Therefore, a stepped handover edge sealing will appear at this location. The heat sealing mold is basically on a horizontal plane, and the bag is often broken from here.
Force during packaging: During the packaging process, if excessive force or sharp objects are used to fill or close the bellows bags, the risk of bag rupture increases.
Transportation and storage environment: During transportation, the accordion packaging bag may be squeezed, collided or rubbed, which may cause the bag to rupture. In addition, improper storage conditions (such as high temperature, humidity, or direct sunlight) may also cause damage to the bag's material.
In order to solve the problem of organ packaging bags being easily broken, the following solutions can be considered:
Use a more durable material: Choosing a thicker or stronger film material can increase the bag's durability and resistance to breakage. For example, use higher grammage polyethylene (PE) or polypropylene (PP) materials, or use special films with increased tear or puncture resistance. Considering the mechanical properties such as fabric folding resistance and mechanical stretchability, NY is better than PET, and PET is better than BOPP. Of course, if NY is used instead of PET, the cost will definitely increase. We can also improve the material properties of the accordion bag by increasing the number of structural layers.
Pay attention to the packing process: When packing items, avoid using excessive force or sharp objects to fill or close the bag. Proceeding gently and carefully will reduce the risk of rupture.
Storage and Shipping Notes: Avoid exposing bags to extremes of temperature, humidity, or sunlight during shipping and storage. In addition, packaging bags should be stacked properly to avoid being squeezed, bumped or rubbed.
Increase structural strength: In key parts of the accordion packaging bag, such as the bottom and sides, the structure can be strengthened and double-layered or reinforced materials can be used to increase the strength and durability of the bag.
By combining these solutions, the risk of bellows bag breakage can be reduced and the reliability and durability of the packaging increased. Of course, specific solutions may vary depending on the actual situation, and it is recommended to choose based on needs and item characteristics.
