Changzhou plastic bag manufacturers: 1. Plastic woven bags
Plastic woven bags are composed of polypropylene bags and polyethylene bags according to primary information; according to sewing methods, they are divided into sewn bottom bags and sewn side bottom bags. Currently, it is a packaging material widely used for fertilizers, chemical products, and other items. The main production process is to extrude plastic materials into films, cut them, uniaxially stretch them into flat yarns, and weave them with warp and weft yarns to produce products, commonly known as woven bags.
Changzhou plastic bag manufacturers: 2. Plastic film bags
Plastic bags are made of polyethylene. Plastic bags have indeed brought convenience to our lives, but this temporary convenience has brought long-term harm.
Classified by production materials: high-pressure polyethylene plastic bags, low-pressure polyethylene plastic bags, polypropylene plastic bags, PVC plastic bags, etc.
Classified by shape: vest bags, straight bags, three-dimensional bags, square bottom bags, sealed bags, tape bags, irregular bags, etc.
Changzhou plastic bag manufacturers: 3. Composite packaging bags
Combining materials with different characteristics improves the breathability, moisture permeability, oil resistance, water resistance, and drug resistance of the packaging material, thus exhibiting insect-proof, dust-proof, antimicrobial, light-proof, fragrance-proof, and odor-proof properties, heat resistance, cold resistance, impact resistance, good mechanical strength and processing applicability, and good printing and decoration effects.
Classified by packaging method: three-side seal, yin and yang bags, middle seal, pillow bags, five-side seal bags, stand-up pouches, zipper bags, straw bales, rolls, covering materials, etc. Classified by function: high-shade barrier bags, cooking film bags, anti-static film bags, antibacterial film bags, anti-fog film bags, vacuum bags, chemical film bags, deoxygenated packaging film bags, and modified atmosphere packaging film bags, etc.
Classified by raw materials: laser-plated aluminum film paper data, laser transfer paper data, paper composite data, aluminum composite data, plastic composite data, fabric composite data, etc.
Changzhou plastic bag manufacturers: The quality of plastic packaging bags is very important.
When we go shopping, the commonly used packaging may be plastic bags. If we are careful, we will find that many businesses choose to print their logos on plastic bags. Many times, after we buy some high-quality or beautifully designed plastic bags, we choose to reuse them. When reused, it is also attributed to intangible commercial advertising.
For Changzhou plastic bag manufacturers, when customizing plastic packaging bags, they can choose high-quality plastic bags or ordinary plastic bags. For customers, if they buy the same thing, when they use the plastic bag, the smell of the plastic bag may be short-lived, so they will not patronize again, and the company will lose many customers invisibly. The reason for this phenomenon is actually very simple. It is nothing more than that merchants do not know how to choose plastic bags for customization, resulting in being cheated and providing customers with low-quality plastic bags. Another reason is that merchants choose lower-priced plastic bags to reduce sales costs, so the quality cannot be guaranteed. No matter what the reason, the result is the same, that is, customer loss. Therefore, the quality of plastic bags directly affects customers' image of us and thus determines whether to shop.
