【 Abstract 】 :
Due to the uneven technology of domestic flexible packaging companies, the production of special-shaped bags is a big problem for many flexible packaging companies, and even some companies have received such orders but have to give up because they do not have enough technical support. Today, Goolien Packaging, a professional flexible packaging manufacturer, briefly introduces the production of special-shaped bags and the performance of related equipment for the reference of production enterprises in need.

With the growing demand for plastic bags in society, plastic bags are constantly covering the market with their own inherent colorful, novel patterns, easy to use and other characteristics, and the market has also put forward higher requirements for plastic bags. Not only requires the design to be innovative in order to attract attention, but also to have high barrier performance to maintain the freshness of the contents, but also requires the shape of the bag to be ever-changing.

Therefore, once the special-shaped bag came out, it quickly attracted people's attention with its unique shape and distinct personality. In the supermarket, a wide range of goods let us overwhelmed, all kinds of plastic packaging bags (especially special-shaped packaging) let us experience a visual enjoyment, but also let us deeply feel that plastic flexible packaging has a huge market.

Due to the uneven technology of domestic flexible packaging companies, the production of special-shaped bags is a big problem for many flexible packaging companies, and even some companies have received such orders but have to give up because they do not have enough technical support. Today, Goolien Packaging, a professional flexible packaging manufacturer, briefly introduces the production of special-shaped bags and the performance of related equipment for the reference of production enterprises in need.
1. Types of special-shaped bags
① Three-sided sealed special-shaped bag
Directly cut out a variety of patterns on the three-sided sealing bag to meet the requirements of daily chemical, food, etc. to reflect the intuitive and distinctive personality of the product. For example, the shape of various fruit slices (mango slices, etc.) packaging bags is designed into the corresponding fruit shape (mango shape, etc.)

② Self-supporting special-shaped bag
 
By filling the bottom, various shapes of special-shaped bags can stand, fully reflecting the three-dimensional sense of special-shaped bags, and convenient for the placement of shelves in supermarkets or shopping malls.

③ Self-supporting special-shaped bag with zipper
 
The Gala chain is based on the unique shape of the special-shaped bag so that the bag can be opened repeatedly. Generally suitable for some light dry items, such as candy, dried fruit, chocolate, cookies, jelly, tea and so on.

④ Self-supporting special-shaped bag with suction nozzle valve
 
The function of adding a nozzle valve is to facilitate the dumping of the contents, and the product after adding the nozzle can be repeatedly sealed, meaning that it can be opened and used several times. This shaped bag is suitable for liquid drinks, body wash, shampoo, ketchup, cooking oil and other liquid products that need to be opened several times.

⑤ Imitation suction mouth type of independent special-shaped bag
 
There is no additional nozzle valve added in the packaging design, but the production characteristics of the special-shaped bag are used to design and produce a shape similar to the nozzle to achieve the purpose of convenient use. It is generally used for liquid packaging, but once opened, it cannot be sealed again.

2.The structure of the special-shaped bag
Special-shaped bags are similar to ordinary flexible packaging bags, the main structure is PET/PE, PET/CPP, BOPP/PE, BOPP/VMPET/PE, PET/Al/NY/PE, PET/NY/PE and other structures, and the printing and composite process is similar to ordinary packaging bags.

3.Special-shaped bag production and equipment
The molding of some special-shaped bags of flexible packaging enterprises is to use the method of making bags on the bag making machine, and then punching out the special-shaped shape under the line, and then carrying out the necessary trimming to complete the production of special-shaped bags. This method wastes a lot of manpower and material resources, and the production efficiency is not high. Now there is an auxiliary equipment of the bag making machine on the market - die cutting machine, which is specially used for the production of special-shaped bags. It is mainly driven by a servo motor, with light, electricity, gas, PLC signal can be well connected with the bag making machine, and to achieve online synchronous die-cutting, can well ensure the precision of special-shaped bag making. There is no need for follow-up processing offline, and it is equipped with the function of online delivery of finished products and automatic winding of cutting edge, which greatly improves the efficiency of special-shaped bag making and reduces production losses. Now there are many manufacturers in the country are producing such machines, do a more successful South China Sea Bocheng and other enterprises.
The special-shaped bag breaks through the shackles of the traditional square bag and turns the straight edge of the bag into a curved edge, thus reflecting a different design style. It has the characteristics of novel, simple, clear, easy to identify, highlighting the brand image, etc., and also represents the trend direction of plastic flexible packaging. At present, some large domestic flexible packaging manufacturers have been equipped with corresponding equipment for the production of professional special-shaped bags. It is believed that with the development of bag-making technology and equipment, with the continuous popularization of die-cutting equipment, the production of special-shaped bags will no longer be a problem for flexible packaging enterprises, and special-shaped bags will show a flourishing scene everywhere.
