聚乙烯（PE）材质：作为世界公认的接触食品材料，聚乙烯材质的塑料袋、无味、无臭，完全符合食品包装卫生标准。它具有出色的防潮性能，能够有效阻挡外界湿气侵入，保持食品的干燥与新鲜。在抗氧方面，PE 塑料袋也有不错的表现，可延长食品的保质期。其耐酸、耐碱特性，使其在接触一些带有酸碱性质的物品时，不易被腐蚀损坏。PE 塑料袋耐寒性能良好，在低温环境下依然能保持一定的柔韧性，不会变脆破裂。不过，其气密性相对一般，热封性虽优异，但对于一些对气密性要求极高的产品来说，可能需要进一步改进。在实际应用中，PE 塑料袋常用于电子、电器、五金、塑胶、服装、鞋子等产品的包装，尤其是食品包装领域，如各类零食包装袋、生鲜食品保鲜袋等。

Polyethylene (PE) material: As the world's recognized best material for contact with food, polyethylene plastic bags are non-toxic, odorless, and completely comply with food packaging hygiene standards. It has excellent moisture resistance and can effectively block external moisture from entering, keeping food dry and fresh. In terms of antioxidant properties, PE plastic bags also have good performance, which can extend the shelf life of food. Its acid and alkali resistance properties make it less susceptible to corrosion and damage when in contact with objects with acidic or alkaline properties. PE plastic bags have good cold resistance and can still maintain a certain degree of flexibility in low temperature environments without becoming brittle or breaking. However, its airtightness is relatively average, and although its heat sealing performance is excellent, for some products that require extremely high airtightness, further improvement may be needed. In practical applications, PE plastic bags are commonly used for packaging electronic, electrical, hardware, plastic, clothing, shoes and other products, especially in the field of food packaging, such as various snack packaging bags, fresh food preservation bags, etc.

聚丙烯（PP）材质：PP 塑料袋俗称 “百折胶”，根据引发剂和聚合工艺的不同，分为等规聚丙烯和无规聚丙烯。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，这赋予了它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，应用相对较少。PP 塑料袋袋身较硬，但透明度比较高，呈现出清晰的视觉效果，并且具有热封性，流延高温膜适用于蒸煮包装。在生活中，PP 材料常用于水管、包装胶袋、玩具、医疗器材等成型品的包装，例如一些硬质的塑料玩具包装袋、医疗用品包装袋等。

Polypropylene (PP) material: PP plastic bags, commonly known as "100 fold glue", are divided into isotactic polypropylene and random polypropylene according to different initiators and polymerization processes. Isotactic polypropylene is prone to forming crystalline states, with a crystallinity of over 95% and a molecular weight between 80000 and 150000, which endows it with excellent heat and solvent resistance. Random polypropylene is a non crystalline, slightly viscous white wax like substance at room temperature, with a low molecular weight ranging from 3000 to 10000. Its structure is irregular and lacks cohesion, making it relatively less commonly used. PP plastic bags have a relatively hard body, but high transparency, presenting a clear visual effect, and have heat sealing properties. The cast high-temperature film is suitable for steaming and cooking packaging. In daily life, PP material is commonly used for packaging molded products such as water pipes, packaging bags, toys, medical equipment, etc., such as some hard plastic toy packaging bags, medical supplies packaging bags, etc.

聚氯乙烯（PVC）材质：PVC 塑料袋具有耐热性、韧性和延展性。其表面膜的上层是漆，中间的主要成分是聚氯乙烯，下层是背涂粘合剂。PVC 是一种深受喜爱、颇为流行且广泛应用的合成材料。然而，它的热稳定性和耐光性较差，在 140℃以上即可开始分解并放出氯化氢（HCl）气体，致使 PVC 变色。不过，其电绝缘性优良，一般不会燃烧。PVC 塑料袋袋身有软也有硬，可根据顾客需求订料，透明度也可按需选择，有超透明料、普通料和磨沙料等不同类型。它的拉力好，不容易扯烂，也不容易爆口。硬的 PVC 塑料袋常用于标签制作，软的则常用于手袋、化妆包、等包装。

Polyvinyl chloride (PVC) material: PVC plastic bags have heat resistance, toughness, and ductility. The top layer of its surface facial mask is paint, the main component in the middle is PVC, and the bottom layer is back coated adhesive. PVC is a beloved, popular, and widely used synthetic material. However, its thermal stability and light resistance are poor, and it can start to decompose and release hydrogen chloride (HCl) gas above 140 ℃, causing PVC to change color. However, it has excellent electrical insulation and generally does not burn. The body of PVC plastic bags can be soft or hard, and can be customized according to customer needs. Transparency can also be selected according to needs, with different types such as ultra transparent materials, ordinary materials, and abrasive materials. It has good tensile strength, is not easily torn apart, and is not prone to bursting. Hard PVC plastic bags are commonly used for label making, while soft ones are commonly used for packaging bags such as handbags, makeup bags, and designer brands.

Other materials:

OPP 材质：OPP 塑料袋透明度极高，是所有常见塑料材质中为透亮的，具有防尘功能，能显著提高被包装产品的价值感。在产品展示中，可使产品一目了然，因此常用于商品销售外包装，起到防尘、保护、美化的作用。但它袋身脆，拉力弱，易爆口，且印刷容易脱色。在首饰、玉石、文具、玩具、餐具、厨房用具、服装等领域的包装中经常能看到 OPP 塑料袋的身影。

OPP material: OPP plastic bags have extremely high transparency and are the most transparent among all common plastic materials. They have dust-proof function and can significantly enhance the value of the packaged products. In product display, it can make the product clear at a glance, so it is commonly used for product sales packaging, which plays a role in dust prevention, protection, and beautification. But its bag body is the most brittle, with weak tensile strength, explosive mouth, and the printing is the easiest to fade. OPP plastic bags are often seen in packaging for jewelry, jade, stationery, toys, tableware, kitchen utensils, clothing, and other fields.

PO 材质：由高密度聚乙烯（HDPE）吹塑成型，，手感似蜡，具有优良的耐低温性能（使用温度可达 - 70 ~ - 100℃），化学稳定性好，能耐大多数酸碱的侵蚀，常温下不溶于一般溶剂，吸水性小，电绝缘性能优良。不过，聚乙烯对于化学与机械作用较为敏感，耐热老化性差。PO 塑料袋袋身较脆，透明度不够高，比 PE 料要朦胧一些，有点透白色，拉力也不是很好，主要用于小闹钟、皮带、电子表等的内包装。

PO material: blow molded from high-density polyethylene (HDPE), non-toxic, with a wax like feel, excellent low temperature resistance (minimum operating temperature can reach -70~-100 ℃), good chemical stability, resistance to most acid and alkali corrosion, insoluble in general solvents at room temperature, low water absorption, and excellent electrical insulation performance. However, polyethylene is sensitive to chemical and mechanical reactions and has poor heat aging resistance. The body of the PO plastic bag is brittle, the transparency is not high enough, and it is slightly hazy compared to PE material. It is a bit translucent white and the tensile strength is not very good. It is mainly used for inner packaging of small alarms, belts, electronic watches, etc.

CPE 材质：CPE 塑料袋是电子产品常用的包装胶袋，如 Ipad 平板电脑、Iphone 手机、PSP 掌上游戏机等。此类胶袋具有磨砂、光滑两面，手感舒适柔软，包装呈现出高档质感，是一种相对昂贵、可使产品显得更高档、更奢华的包装袋。它也叫磨砂 EVA，呈半透明状，具有消光、低毒、效果。

CPE material: CPE plastic bags are commonly used packaging bags for electronic products, such as iPad tablets, iPhone phones, PSP handheld game consoles, etc. This type of plastic bag has frosted and smooth sides, comfortable and soft feel, and presents a high-end texture in packaging. It is a relatively expensive packaging bag that can make products appear more upscale and luxurious. It is also called frosted EVA, which is semi transparent and has extinction, low toxicity, and environmental protection effects.

聚酯膜（PET）材质：PET 具有抗张力，耐热 60 - 150 度，气密性良好，适合蒸煮性，但没有热封性。它具有很好的光学性能、优良的耐磨耗摩擦性和尺寸稳定性及电绝缘性，强度大、透明性好、、防渗透、质量轻、生产效率高，因而受到广泛应用。不过，PET 不适合独立成型包装袋，常作为各类食品、药品、纺织品、精密仪器、电器元件等包装表面的合成材料。

Polyester film (PET) material: PET has tensile strength, heat resistance of 60-150 degrees, good air tightness, suitable for steaming and boiling, but does not have heat sealing properties. It has good optical performance, excellent wear resistance, friction resistance, dimensional stability, and electrical insulation. It has high strength, good transparency, non toxicity, impermeability, light weight, and high production efficiency, and is therefore widely used. However, PET is not suitable for independently forming packaging bags and is often used as a synthetic material for packaging surfaces of various foods, drugs, textiles, precision instruments, electrical components, etc.
