Many customers often do not know how to choose plastic packaging bags. On the one hand, they are not clear about the material of plastic packaging bags, and on the other hand, they are not familiar with the bag type selection and production process of plastic packaging bags. There are also some customers who worry about the safety, hygiene and environmental protection of plastic packaging. Below, professional flexible packaging manufacturers will give you a detailed answer. As the name suggests, plastic packaging bags are made of plastic as raw materials and are widely used in packaging products in daily production and life. Commonly used plastic packaging bags are mostly polyethylene (PE), oriented polypropylene (OPP), cast polypropylene (CPP), polyethylene terephthalate (PET), nylon (PA), aluminum foil (AL) These films can be used to contain food, clothing, hardware, electronics, cosmetics and other products. The confirmation of the material of plastic packaging bags seems simple, but an ideal packaging material needs to fully consider the following aspects: the adaptability of printing, the barrier properties of materials, the heat sealing properties of materials, etc. Different products are suitable for different materials. Many times, plastic packaging bags are not made of one material. In order to obtain better performance, multiple materials are compounded to make compound packaging bags to package products. Common types of composite packaging bags are: paper/plastic composite, plastic/plastic composite, aluminum/plastic composite, etc. The number of composite substrate layers can be two layers, three layers, four layers, five layers or even more. According to the type and thickness of the composite plastic film substrate, the number and order of the combined layers, and the composite method, many types of composite packaging bags can be formed. Plastic packaging bags can be divided into three-side sealing bags, middle-sealing bags, four-side sealing bags, eight-side sealing bags and stand-up bags according to the bag type. Custom-made plastic packaging bags is a very rigorous work. A good packaging bag needs to fully consider the needs of production, packaging, transportation, sales and other links.

The company has a professional R&D and design team, which can provide customers with bag design and packaging material selection for free, and create unique plastic packaging bags for your products.

To make a custom plastic bag, it is necessary to confirm the size of the bag. A more feasible method is to refer to the product packaging bag of the same industry. Some special bag types, such as hem bags and flat bottom bags, also need to measure the dimensions of the hem and the bottom of the bag.
