With the continuous development of the packaging industry, flexible packaging products have gradually shown a trend to replace traditional packaging.
Composite membranes and packaging bags are important members of today's soft plastic packaging products. With the continuous launch of new products in many fields such as food industry and pharmaceutical industry, the original packaging bags are increasingly unable to meet the packaging needs of all products. Seeking breakthroughs in different bag types, such as shaped bags, octagonal bags, organ bags, etc. are all packaging bags derived from the packaging industry to adapt to product properties and packaging requirements.
The bag with a special-shaped bag has obvious advantages compared with the ordinary soft plastic bag. With some zippers and nozzles, it is a new type of bag with a zipper shaped self-standing bag and a suction-shaped shaped stand-up pouch. It is convenient for consumers to use, but how to design and produce a qualified and excellent shaped bag that meets the product packaging requirements is more troublesome than the average bag.
For soft plastic packaging products, special-shaped bags also need to follow the basic planning guidelines. The choice of packaging materials needs to be safe, non-toxic and environmentally friendly, and also needs to consider the packaging structure and packaging performance of the products.
