What are the advantages of self-standing zipper bags?

The self-standing zipper bag is a kind of packaging bag that uses plastic as raw material to produce various daily necessities. It is widely used in daily life and industrial production, but its convenience has brought long-term harm. Commonly used self-standing zipper bags are made of polyethylene film and can be used to hold food. Let’s take a look at the advantages of self-operated zipper bags.

1. Physical protection: Items stored in self-standing zipper bags should avoid extrusion, impact, vibration, temperature differences, etc.

2. Shell protection: The shell can isolate items from oxygen, water vapor, stains, etc. Leak protection is also a necessary factor in packaging design. Some packages include desiccants or deoxidizers to extend shelf life. Vacuum packaging, or removing the air from the bag, is also a primary packaging method. Keeping it clean, fresh and safe during the shelf life is the main function of the packaging bag.

3. Pack or place in the same self-service zipper bag: Inserting small items of the same type into one package is a great way to save volume. Powders and granular objects require packaging.

4. Information: Self-service zipper bags and labels tell people how to use, transport, recycle or dispose of packages or items.

5. Marketing: Marketing often uses box labels to encourage potential buyers to purchase an item. Over the decades, packaging design has become a critical and ever-changing phenomenon. Highlights of marketing and graphic design are applied to the outer packaging boxes and sales presentations.

6. Safety: Self-standing zipper bags play an important role in reducing transportation safety risks. Bags also avoid being classified as other goods. Some are covered with anti-counterfeiting signs to protect corporate interests from losses. Self-standing zipper bags can have labels such as laser marking, special colors, and SMS authentication. In addition, in order to prevent theft, retailers attach electronic monitoring labels to packaging bags and wait for consumers to take them away for degaussing at the door of the store.

7. Convenience: Self-standing zipper bags can be easily added, loaded, unloaded, stacked, displayed, sold, opened, repackaged, used and reused.

8. Local Control: A single package helps to accurately control the global situation. You can also easily calculate your self-service zipper bag sales.

Self-standing spout bag making process requirements:

1. Heat sealing temperature

The factors to be considered when setting the heat sealing temperature are: first, the characteristics of the heat sealing material; second, the film thickness; third, the number of heat sealing and hot pressing and the size of the heat sealing area. Generally speaking, when the same part is hot pressed multiple times, the heat sealing temperature can be appropriately reduced.

2. Heat sealing pressure

Independent zipper bag manufacturers: Appropriate pressure must be applied during the heat sealing process to promote adhesion of the heat cover material. However, if the pressure is too high, the molten material will be extruded, which will not only affect the flatness of the bag, fault analysis and troubleshooting, but also affect the heat sealing effect of the bag and reduce the heat sealing strength.

3. Heat sealing time

Independent zipper bag manufacturer: The heat sealing time is not only related to the heat sealing temperature and pressure, but also to the performance of the heat sealing material, heating method and other factors. The specific operations should be adjusted according to different equipment and materials during actual commissioning.
