Must-read for Custom Plastic Packaging Bags

Many customers often don't know how to choose plastic packaging bags. On the one hand, they are unclear about the material of plastic packaging bags, and on the other hand, they are unfamiliar with the bag type selection and production process of plastic packaging bags. Some customers also worry about issues such as the safety, hygiene, and environmental friendliness of plastic packaging. Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will answer these questions one by one.

As the name suggests, plastic packaging bags are packaging products made of plastic as raw material, widely used in daily production and life. Commonly used plastic packaging bags are mostly made of polyethylene (PE), oriented polypropylene ( OPP ), cast polypropylene ( CPP ), polyethylene terephthalate ( PET ), nylon ( PA ), aluminum foil ( AL ) are made. These films can be used to hold products such as food, clothing, hardware, electronics, and cosmetics.

Confirming the material of plastic packaging bags seems simple, but an ideal packaging material needs to fully consider the following aspects: print adaptability, barrier properties of the material, heat-sealability of the material, etc.

Different products are suitable for different materials. Plastic packaging bags are often not made from a single material; usually, to achieve better performance, multiple materials are compounded to create composite packaging bags. Common types of composite packaging bags include: paper/plastic composite, plastic/ / plastic composite, aluminum/ / plastic composite, etc. The number of layers of the composite substrate can be two, three, four, five, or even more. According to the type and thickness of the composite plastic film substrate, the number and order of combinations, and the compounding method, many types of composite packaging bags can be formed.

Plastic packaging bags can be divided into three-side seal bags, center seal bags, four-side seal bags, eight-side seal bags, and stand-up pouches, etc., according to their bag type.

Customizing plastic packaging bags is a very rigorous task. A good packaging bag needs to fully consider the needs of various stages such as production, packaging, transportation, and sales . Dongguan Shunxingyuan Packaging Products Co., Ltd. is a professional original manufacturer of plastic packaging bags. The company has a professional R&D and design team that can provide free bag type design and packaging material selection for customers, creating unique plastic packaging bags for your products.

When customizing plastic packaging bags, customers are most concerned about the price. However, considering that the requirements for plastic packaging bags differ for each customer, such as thickness, size, material, and printing color, the price also varies. Therefore, Shunxingyuan Packaging recommends clearly defining your needs when customizing plastic packaging bags to obtain an accurate price.

To customize plastic packaging bags, confirm the bag size. A more feasible method is to refer to competitors' product packaging bags. For some special bag types, such as gusseted bags or flat bottom bags, the dimensions of the gusset and the bottom of the bag also need to be measured.
