The back seal bag is a packaging bag for packaging various supplies, which is widely used in daily life and industrial production. With the development of industry, the commodity of the back seal bag itself is becoming more and more prominent. It has become a special product that is no longer affixed to merchandise. All products are indispensable and are widely used products, but the packaging items are different when used, and the shock absorption capacity of the existing back seal bag is reduced. For items that ensure integrity and fragile, then learn about the production method of the back seal bag together below!

Back bag technology implementation elements:

The purpose of the utility model is to solve the problem of poor shock absorption and compression capacity proposed in the background art, and to provide a back-sealed bag.

In order to achieve this object, the present invention provides the following technical solutions. That is, a back-sealed bag comprising the device body. The device body is rectangular, a back seal is provided on the back of the device body, side seals are provided at both ends of the device body, a plastic film layer is installed inside the device body, and the plastic film layer is externally covered with an outer layer, The outer layer is a pattern layer, an inner surface is provided inside the device body, and the inner surface is a fresh-keeping layer.

Both ends of the apparatus main body are provided with serrations.

Preferably, an antistatic layer is attached to the outside of the device main body, and the antistatic layer is an antistatic main layer.

Preferably, an effervescent layer is provided inside the device body, and the effervescent layer is located between the appearance layer and the plastic film layer.

Preferably, a thermal insulation layer is installed inside the device body, and the thermal insulation layer is a nano thermal insulation layer.

Compared with the prior art, the beneficial effect of the back seal bag is that the product is a white peak packaging bag. Compared with other packaging forms, the back seal bag has no cover on both sides of the back seal bag, so the front of the package is relatively beautiful. In the typesetting design, the white body pattern can be designed as a whole to ensure the consistency of the pattern. The antistatic main particle layer used for the antistatic layer can prevent static electricity caused by the insulation performance of the polymer itself, in order to adapt to the product packaging requirements and the production of special anti-static products. It has a good effect on the surface dust of the product. Good anti-static effect, long-lasting efficacy, good dispersibility, small amount of addition, no toxic substances, effervescent layer has a certain degree of elasticity, can reduce the pressure of items during transportation or collision, and serrations can facilitate the original disassembly of the device.

The back-sealed bag clearly and completely describes the technical solutions of the embodiments of the present invention. Obviously, the embodiments are only part of the embodiments of the present invention, not all of the embodiments. According to the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention. Specific usage: This product is a Baifeng packaging bag. Compared with other packaging forms, Baifeng bag has no seal on both sides of the bag, so the front of the package is relatively beautiful. The typesetting design can design the bag pattern as a whole to ensure the consistency of the pattern. The antistatic mother layer used for the antistatic layer can prevent static electricity generated due to the insulation performance of the polymer itself, and adapt to the packaging requirements of the product and the production of special antistatic products.

The above is the production method of the back seal bag, if you need to know more, you can contact us at any time!
