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.

服裝包裝袋分高密度的和低密度的。高密度的更加堅(jiān)韌，透明度高，手感硬挺，相對(duì)較貴。一般給的塑料袋都是高密度PE袋。低密度PE袋就是一般市場(chǎng)賣(mài)菜給的普通的那種摸上去很軟的袋子，品質(zhì)較次，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.

平口袋是由高壓全新PE原料制成，透明有韌性，手感光滑，舒適柔然，全新材料，無(wú)味無(wú)害，適用于服裝的內(nèi)外防塵，生活家居用品，工業(yè)電子產(chǎn)品，五金產(chǎn)品，機(jī)械零件，食品類(lèi)包裝，化妝品，厚重紙品的包裝等多種物品的內(nèi)外防塵防潮作用。

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.

備注：高壓平口袋不是自封袋和自粘袋，就是袋口為雙面齊平且袋口無(wú)封口膠或夾扣，該類(lèi)袋子需配合封口機(jī)/膠帶/卡片/繩子等進(jìn)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.

高壓袋、低壓袋的區(qū)別：高壓塑料袋材質(zhì)：低密度聚乙烯樹(shù)脂（LDPE） 低壓塑料袋材質(zhì)：高密度聚乙烯樹(shù)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)

高壓袋透明度較好，低壓袋是半透明狀。

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

高壓袋手感非常柔軟，低壓袋質(zhì)地較硬，沙沙響。

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

高壓袋的拉力強(qiáng)度、韌性較低壓袋好一些，低壓袋的這些性能也是很好的。

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.

高壓、低壓的相同點(diǎn)：、無(wú)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.

尼龍袋是指以各種聚酰胺為材料的塑料袋，因具體的酰胺材料不同有所差異。但總的來(lái)說(shuō)，外觀(guān)上質(zhì)感好，厚實(shí)，摸上去絲滑柔順。一般用于裝高檔服飾、首飾等商品，相對(duì)較高。

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.

袋與PP袋，OPP袋等的不同：

The difference between bags and PP bags and OPP bags:

袋:是乙烯進(jìn)行加聚而成的高分子有機(jī)化合物。聚乙烯是世界上公認(rèn)的接觸食品材料。、無(wú)味、無(wú)臭，符合食品包裝衛(wèi)生標(biāo)準(zhǔn)。聚乙烯薄膜，輕盈透明，具有防潮、抗氧、耐酸、耐堿、氣密性一般，熱封性?xún)?yōu)異等性能。是塑料包裝印刷用量多、使用廣的膠袋之一。袋身較軟, 但透明度不夠其它料高,比較蒙.,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：俗稱(chēng)：百折膠。聚丙烯是聚α-烯烴的代表，由丙烯聚合而制得的一種熱塑性樹(shù)脂，其單體是丙烯CH2=CH－CH3。根據(jù)引發(fā)劑和聚合工藝的不同，聚丙烯可以分為等規(guī)聚丙烯和無(wú)規(guī)聚丙烯和間規(guī)聚丙烯三種構(gòu)型。等規(guī)聚丙烯易形成結(jié)晶態(tài)，結(jié)晶度高達(dá)95%以上，分子量在8-15萬(wàn)之間，賦予他良好的抗熱和抗溶劑性；無(wú)規(guī)聚丙烯在室溫下是一種非結(jié)晶的、微帶粘性的白色蠟狀物，分子量低，在3000-10000，結(jié)構(gòu)不規(guī)整,缺乏內(nèi)聚力，應(yīng)用較少。袋身較硬, 但透明度比較高, 較清晰, 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、，為透亮，有著防塵、提高被包裝產(chǎn)品價(jià)值的作用。在銷(xiāo)售中可充分展示里面的產(chǎn)品，所以O(shè)PP膠袋產(chǎn)品通常用來(lái)作商品銷(xiāo)售外包裝，既起到保護(hù)作用，又起到美化作用。廣泛應(yīng)用于首飾、口罩、玉石、文具、玩具、餐具、廚房用具、服裝等領(lǐng)域。袋身脆, 透明度, 拉力不夠,但易爆口. 且印刷容易脫色。

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.
