With the increasing demand for plastic flexible packaging, plastic flexible packaging with its inherent bright colors, novel patterns, easy to use features continue to cover the market. The market also puts forward higher requirements for plastic flexible packaging, which not only requires innovative designs to attract more people's attention, but also requires high barrier properties to maintain the freshness of the contents. This also requires the shape of the soft bag is ever-changing, so as soon as the special-shaped bag comes out, it quickly attracts people's attention with its unique shape and distinctive personality. This paper briefly introduces the production of special-shaped bags and the performance of related equipment, for the reference of flexible packaging enterprises:

Types of 1. special-shaped bags

1. The special-shaped bag is sealed on three sides, and various patterns are directly punched and cut on the three-sided sealing bag to meet the requirements of daily chemical products, food and the like, reflecting the intuitive and vivid characteristics of the products. For example, all kinds of fruit packaging bags are designed according to the shape of the fruit.

2. Self-supporting special-shaped bags, through the bottom filling, can make various shapes of special-shaped bags stand up, fully reflect the three-dimensional sense of special-shaped bags, convenient for supermarket or shopping mall shelves.

3. Self-supporting special-shaped bag with zipper. With zipper, the bag can be opened repeatedly according to the unique shape of the special-shaped bag. It is generally suitable for some light dry goods, such as candy, dried fruit, chocolate, biscuits, jelly, tea, etc.

4. Use a self-supporting special-shaped bag with a nozzle to easily pour the contents. Products with nozzles can be sealed repeatedly, that is to say, they can be opened multiple times. This special-shaped bag is suitable for liquid products that need to be opened multiple times, such as liquid beverages, shower gel, shampoo, ketchup, edible oil, etc.

II. Special-shaped bag manufacturing and equipment. In some flexible packaging companies, special-shaped bags are formed by a bag making machine, and the punching machine is used for offline punching, the special-shaped shape is cut off, and then the necessary trimming is performed. This method wastes a lot of manpower and material resources, and the production efficiency is not high. At present, the auxiliary equipment of the bag making machine is die-cutting machine, which is specially used for the production of special-shaped bags. Mainly driven by servo motor, equipped with light, electricity and gas. With the PLC signal, it can be well connected with the bag making machine to realize online synchronous die cutting and ensure the bag making accuracy of the special-shaped bag. There is no need for offline follow-up processing, and it has the functions of online delivery of finished products, trimming, automatic coiling, etc., which greatly improves the bag making efficiency of special-shaped bags.

The special-shaped bag breaks through the shackles of the traditional square bag, turns the straight edge of the bag into a curved edge, embodies different design styles, has the characteristics of novelty, simplicity, clarity, easy identification, and highlights the brand image, and also represents the trend of plastic flexible packaging. direction. At present, some large domestic flexible packaging enterprises have been equipped with the corresponding special-shaped bag production equipment. It is believed that with the development of bag-making technology and equipment and the popularity of die-cutting equipment, the manufacture of special-shaped bags will no longer be a difficult problem for flexible packaging enterprises, and special-shaped bags will blossom everywhere.

Today, Xiao Bian will introduce it here first. Thank you for looking at it. If you need special-shaped bags or multilateral bags, you can contact our company to make them. You will not be disappointed.
