　　可降解塑料袋是指在一定條件下能夠分解為較小的碎片，并終被微生物或自然環(huán)境所降解的塑料袋。

　　Degradable plastic bags refer to plastic bags that can decompose into smaller fragments under certain conditions and ultimately be degraded by microorganisms or the natural environment.

　　根據(jù)不同的材質(zhì)和降解方式，可降解塑料袋可以分為以下幾類：

　　According to different materials and degradation methods, biodegradable plastic bags can be divided into the following categories:

　　生物可降解塑料袋（Biodegradable Plastic Bags）：這種塑料袋通常由天然材料如淀粉、聚乳酸（PLA）、纖維素等制成，具有良好的生物降解性。它們能夠在適當(dāng)?shù)沫h(huán)境中經(jīng)過微生物作用而分解，終轉(zhuǎn)化為二氧化碳、水和肥料。生物可降解塑料袋適用于一次性包裝、輕負載物品的運輸和垃圾袋等。

　　Biodegradable Plastic Bags: These plastic bags are typically made from natural materials such as starch, polylactic acid (PLA), cellulose, etc., and have good biodegradability. They can be decomposed by microbial action in appropriate environments and ultimately converted into carbon dioxide, water, and fertilizer. Biodegradable plastic bags are suitable for disposable packaging, transportation of lightweight items, and garbage bags.

　　光降解塑料袋（Photodegradable Plastic Bags）：這種塑料袋通過添加光敏劑，使其在陽光照射下發(fā)生分解。光降解塑料袋的分解速度取決于光照強度和時間，當(dāng)暴露在陽光下一段時間后，它們會變脆并終分解為碎片。這種塑料袋適用于對生物降解性能要求不高的一次性包裝和輕負載物品的運輸。

　　Photodegradable Plastic Bags: These plastic bags decompose under sunlight by adding photosensitizers. The decomposition rate of photo degradable plastic bags depends on the intensity and time of light exposure. After being exposed to sunlight for a period of time, they will become brittle and eventually decompose into fragments. This type of plastic bag is suitable for the transportation of disposable packaging and lightweight items that do not require high biodegradability.

　　氧降解塑料袋（Oxo-degradable Plastic Bags）：氧降解塑料袋通過在塑料中添加特定的氧化劑使其具有降解性。這種塑料袋在受到氧化劑和熱量的作用下，發(fā)生分解并終降解成較小的碎片。氧降解塑料袋適用于一次性包裝、輕負載物品的運輸和垃圾袋等。

　　Oxo degradable plastic bags: Oxo degradable plastic bags are made biodegradable by adding specific oxidants to the plastic. This type of plastic bag decomposes and eventually breaks down into smaller fragments under the action of oxidants and heat. Oxygen degradable plastic bags are suitable for disposable packaging, transportation of lightweight items, and garbage bags.

　　混合降解塑料袋（Blend Degradable Plastic Bags）：混合降解塑料袋是將多種可降解材料混合在一起制成的。通過利用各種材料的優(yōu)勢，實現(xiàn)更好的降解性能和強度。這類塑料袋的應(yīng)用場景與其他類型的可降解塑料袋類似，適用于一次性包裝、輕負載物品的運輸和垃圾袋等。

　　Blend Degradable Plastic Bags: Blend Degradable Plastic Bags are made by mixing multiple biodegradable materials together. By utilizing the advantages of various materials, better degradation performance and strength can be achieved. The application scenarios of this type of plastic bag are similar to other types of biodegradable plastic bags, suitable for disposable packaging, transportation of lightweight items, and garbage bags.

　　對于可降解塑料袋，常見的材質(zhì)包括但不限于：

　　For biodegradable plastic bags, common materials include but are not limited to:

　　淀粉基塑料：由淀粉為主要原料制成，能夠與微生物相互作用而降解。

　　Starch based plastics: made mainly from starch and capable of degrading through interaction with microorganisms.

　　聚乳酸（PLA）：由玉米、甘蔗等植物原料提取制成，具有良好的生物降解性能。

　　Polylactic acid (PLA): extracted from plant materials such as corn and sugarcane, it has good biodegradability.

　　纖維素基塑料：使用纖維素作為主要原料，具有較高的生物降解性。

　　Cellulose based plastics: using cellulose as the main raw material, they have high biodegradability.

　　生物基聚合物：使用生物基原料如植物油或酒精制成，與傳統(tǒng)塑料相比，其生產(chǎn)過程產(chǎn)生的溫室氣體較少。

　　Biobased polymers: Made from biobased materials such as vegetable oil or alcohol, their production process produces less greenhouse gases compared to traditional plastics.

　　常見的可降解塑料袋尺寸與適用場景包括：

　　Common sizes and applicable scenarios of biodegradable plastic bags include:

　　1、20 cm x 30 cm：這是較小的可降解塑料袋尺寸，適用于零食、文具、小件衣物等小型物品的包裝。

　　1. 20 cm x 30 cm: This is a smaller biodegradable plastic bag size suitable for packaging small items such as snacks, stationery, and small clothing.

　　2、25 cm x 35 cm：這種尺寸的可降解塑料袋適用于輕負載物品如衣物、文具等的包裝和運輸。

　　2. 25 cm x 35 cm: This size of biodegradable plastic bag is suitable for packaging and transportation of lightweight items such as clothing, stationery, etc.

　　3、30 cm x 40 cm：適用于中等大小的物品，如書籍、文件夾、家居用品等。

　　3. 30 cm x 40 cm: Suitable for medium-sized items such as books, folders, household items, etc.

　　4、40 cm x 50 cm：適用于一些較大但不太重的物品如衣物、枕頭、毛巾等。

　　4. 40cm x 50cm: Suitable for larger but not too heavy items such as clothing, pillows, towels, etc.

　　5、50 cm x 60 cm：更大的尺寸適用于裝載大件商品如靠墊、床單、家居用品等。

　　5. 50 cm x 60 cm: The larger size is suitable for loading large items such as cushions, bed sheets, household items, etc.

　　需要注意的是，尺寸和適用場景會根據(jù)實際需求和要求而有所變化?？山到馑芰洗膹V泛應(yīng)用可以減少對環(huán)境的污染，促進可持續(xù)發(fā)展。

　　It should be noted that the size and applicable scenarios may vary according to actual needs and requirements. The widespread use of biodegradable plastic bags can reduce environmental pollution and promote sustainable development.

　　然而，仍然需要注意正確的使用和回收處理，以充分發(fā)揮其優(yōu)勢。

　　However, it is still necessary to pay attention to proper use and recycling to fully leverage its environmental advantages.
