The thickness unit of clothing packaging bag is "silk". The more silk, the thicker and heavier it is, and the better its load-bearing capacity is. 1 wire=0.01mm, the general supermarket shopping bag is double-sided and 5-wire, the less than 5-wire is the ordinary thin type, the 5-wire is the medium thick type, the 7-wire and 10-wire are the thickened type, and the 14-wire thickness is the extra-thick type, which has super bearing capacity and can be used repeatedly.

服装包装袋分高密度的和低密度的。高密度的更加坚韧，透明度高，手感硬挺，相对较贵。一般给的塑料袋都是高密度PE袋。低密度PE袋就是一般市场卖菜给的普通的那种摸上去很软的袋子，品质较次，透明度差，便宜。

Clothing packaging bags are divided into high density and low density. The high-density ones are more tenacious, transparent, hard to handle, and relatively expensive. Generally, the plastic bags given by supermarkets are high-density PE bags. Low-density PE bag is the most common kind of soft bag sold in the general market. It is of inferior quality, poor transparency and cheap price.

平口袋是由高压全新PE原料制成，透明有韧性，手感光滑，舒适柔然，全新材料，无味无害，适用于服装的内外防尘，生活家居用品，工业电子产品，五金产品，机械零件，食品类包装，化妆品，厚重纸品的包装等多种物品的内外防尘防潮作用。

The flat bag is made of high pressure new PE raw material, transparent and flexible, smooth, comfortable and soft, new material, non-toxic, tasteless and harmless. It is applicable to the internal and external dust and moisture prevention of clothing, household products, industrial electronic products, hardware products, mechanical parts, food packaging, cosmetics, heavy paper packaging and other items.

备注：高压平口袋不是自封袋和自粘袋，就是袋口为双面齐平且袋口无封口胶或夹扣，该类袋子需配合封口机/胶带/卡片/绳子等进行封口。

Note: The high-pressure flat bag is not a self-sealing bag or self-adhesive bag, but the bag mouth is flush on both sides and there is no sealing adhesive or clip at the bag mouth. Such bags need to be sealed with a sealing machine/tape/card/rope, etc.

高压袋、低压袋的区别：高压塑料袋材质：低密度聚乙烯树脂（LDPE） 低压塑料袋材质：高密度聚乙烯树脂（HDPE）

Difference between high-pressure bag and low-pressure bag: high-pressure plastic bag material: low-density polyethylene resin (LDPE) low-pressure plastic bag material: high-density polyethylene resin (HDPE)

高压袋透明度较好，低压袋是半透明状。

The high pressure bag is transparent, and the low pressure bag is translucent.

高压袋手感非常柔软，低压袋质地较硬，沙沙响。

The high pressure bag feels very soft, and the low pressure bag is hard and rusty.

高压袋的拉力强度、韧性较低压袋好一些，低压袋的这些性能也是很好的。

The tensile strength and toughness of high-pressure bags are better than those of low-pressure bags, and these properties of low-pressure bags are also very good.

高压、低压的相同点：、无味、不易透水且不溶于油等。

The similarities between high pressure and low pressure: non-toxic, odorless, impermeable and insoluble in oil.

尼龙袋是指以各种聚酰胺为材料的塑料袋，因具体的酰胺材料不同有所差异。但总的来说，外观上质感好，厚实，摸上去丝滑柔顺。一般用于装高档服饰、首饰等商品，相对较高。

Nylon bags refer to plastic bags made of various polyamides, which vary according to specific amide materials. But in general, the appearance is good in texture, thick, and silky and smooth to the touch. It is generally used for high-end clothing, jewelry and other goods, and the price is relatively high.

袋与PP袋，OPP袋等的不同：

The difference between bags and PP bags and OPP bags:

袋:是乙烯进行加聚而成的高分子有机化合物。聚乙烯是世界上公认的接触食品材料。、无味、无臭，符合食品包装卫生标准。聚乙烯薄膜，轻盈透明，具有防潮、抗氧、耐酸、耐碱、气密性一般，热封性优异等性能。是塑料包装印刷用量多、使用广的胶袋之一。袋身较软, 但透明度不够其它料高,比较蒙.,拉力好不易爆口。

Bag: It is a high molecular organic compound formed by the addition of ethylene. Polyethylene is recognized as the best material in contact with food in the world. It is non-toxic, tasteless and odorless, and conforms to the hygienic standard of food packaging. Polyethylene film, light and transparent, has the properties of moisture resistance, oxygen resistance, acid resistance, alkali resistance, general air tightness and excellent heat sealing. It is one of the most widely used plastic bags for plastic packaging and printing. The bag body is soft, but the transparency is not high enough for other materials, The tension is not easy to burst.

袋：俗称：百折胶。聚丙烯是聚α-烯烃的代表，由丙烯聚合而制得的一种热塑性树脂，其单体是丙烯CH2=CH－CH3。根据引发剂和聚合工艺的不同，聚丙烯可以分为等规聚丙烯和无规聚丙烯和间规聚丙烯三种构型。等规聚丙烯易形成结晶态，结晶度高达95%以上，分子量在8-15万之间，赋予他良好的抗热和抗溶剂性；无规聚丙烯在室温下是一种非结晶的、微带粘性的白色蜡状物，分子量低，在3000-10000，结构不规整,缺乏内聚力，应用较少。袋身较硬, 但透明度比较高, 较清晰, 拉力不是很好, 易爆口。

Bag: commonly known as 100% discount glue. Polypropylene is poly α- The representative of olefin is a thermoplastic resin prepared by polymerization of propylene. Its monomer is propylene CH2=CH-CH3. According to different initiators and polymerization processes, polypropylene can be divided into three configurations: isotactic polypropylene, random polypropylene and syndiotactic polypropylene. Isotactic polypropylene is easy to form crystalline state, with crystallinity of more than 95% and molecular weight of between 80000 and 150000, which endows it with good heat resistance and solvent resistance; Random polypropylene is an amorphous, slightly sticky white wax at room temperature, with low molecular weight (3000-10000), irregular structure, lack of cohesion and less application. The bag body is hard, but the transparency is high and clear, the tension is not very good, and the mouth is explosive.

袋：透明度、，为透亮，有着防尘、提高被包装产品价值的作用。在销售中可充分展示里面的产品，所以OPP胶袋产品通常用来作商品销售外包装，既起到保护作用，又起到美化作用。广泛应用于首饰、口罩、玉石、文具、玩具、餐具、厨房用具、服装等领域。袋身脆, 透明度, 拉力不够,但易爆口. 且印刷容易脱色。

Bag: The transparency is the best, the highest, and the most transparent. It can prevent dust and improve the value of packaged products. The products inside can be fully displayed during sales, so OPP plastic bag products are usually used as the outer packaging for commodity sales, which not only plays a protective role, but also plays a beautification role. It is widely used in jewelry, masks, jade, stationery, toys, tableware, kitchen utensils, clothing and other fields. The body of the bag is the most brittle, transparent and not enough tensile force, but it is the most explosive And printing is the easiest to decolor.
