济南的复合塑料袋通常由多种材质复合而成，常见的有以下几种：

Composite plastic bags in Jinan are usually made of multiple materials, including the following:

BOPP/CPP 复合袋：由双向拉伸聚丙烯薄膜（BOPP）和流延聚丙烯薄膜（CPP）复合而成。这种复合袋防潮能力强，韧性好，有较强的拉力，耐水耐油性能强，透明度高，无味，但耐寒、耐热性能较差，主要应用在熟食品、茶叶、油性食物以及饼干、糖果、方便面等干燥食品包装。

BOPP/CPP composite bag: composed of biaxially oriented polypropylene film (BOPP) and cast polypropylene film (CPP). This composite bag has strong moisture resistance, good toughness, strong tensile strength, strong water and oil resistance, high transparency, non-toxic and odorless properties, but poor cold and heat resistance. It is mainly used for packaging cooked food, tea, oily food, as well as dry food such as biscuits, candies, instant noodles, etc.

BOPA6/LDPE 复合袋：由双向拉伸尼龙 6 薄膜（BOPA6）和低密度聚乙烯薄膜（LDPE）复合而成。具有耐高温、无味、防潮、耐油的特点，不过透明度很差，主要应用在熟食品、速冻食品等包装，可以加热、冷藏、蒸煮。

BOPA6/LDPE composite bag: composed of biaxially oriented nylon 6 film (BOPA6) and low-density polyethylene film (LDPE). It has the characteristics of high temperature resistance, non toxicity, odorlessness, moisture resistance, and oil resistance, but its transparency is poor. It is mainly used in packaging of cooked and frozen foods, and can be heated, refrigerated, and steamed.

PET/PE 复合袋：由聚对苯二甲酸乙二酯薄膜（PET）和聚乙烯薄膜（PE）复合而成。防氧化性能好，防潮，耐寒，透明度较高，无味，应用在各种充气食品包装，服装、针织品、日常生活用品包装，也可用作购物袋、保鲜袋、礼品袋等。

PET/PE composite bag: composed of polyethylene terephthalate film (PET) and polyethylene film (PE). Good oxidation resistance, moisture resistance, cold resistance, high transparency, non-toxic and odorless. It is used in various inflatable food packaging, clothing, knitwear, daily necessities packaging, as well as shopping bags, fresh-keeping bags, gift bags, etc.

纯铝袋和镀铝袋：包括纸铝复合袋等。如 opp/al/pe、pet/al/pe 等纯铝复合袋，以及 pet/vmpet/pe、vmpet/cpp 等镀铝复合袋，具有良好的阻隔性、遮光性、保香性等，可用于对包装要求较高的产品，如一些高档食品、药品等的包装。

Pure aluminum bags and aluminum plated bags: including paper aluminum composite bags, etc. Pure aluminum composite bags such as OPP/Al/PE and PET/Al/PE, as well as aluminum plated composite bags such as PET/VMPET/PE and VMPET/CPP, have good barrier properties, light blocking properties, and fragrance retention. They can be used for products with high packaging requirements, such as high-end food and medicine packaging.

济南对塑料袋的使用有明确的要求，根据《济南市进一步加强塑料污染治理实施方案》，到 2020 年底，城市建成区的、、药店、书店等场所及餐饮打包外卖服务和各类展会活动，禁止使用不可降解塑料袋；到 2025 年底，城市建成区集贸市场禁止使用不可降解塑料袋。上述常见的复合塑料袋材质中，如果是采用可降解的树脂原料生产，并且符合相关标准中关于、等方面的要求，如在生物分解率、重金属含量、溶剂残留量等指标上达标，那么就是符合济南要求的。如果是不可降解的复合塑料袋，在济南规定的禁止使用范围内就不符合要求。

Jinan has clear environmental requirements for the use of plastic bags. According to the "Implementation Plan for Further Strengthening Plastic Pollution Control in Jinan City", by the end of 2020, the use of non degradable plastic bags will be prohibited in shopping malls, supermarkets, pharmacies, bookstores and other places in urban built-up areas, as well as in food and beverage delivery services and various exhibition activities; By the end of 2025, the use of non degradable plastic bags will be prohibited in urban built-up area markets. Among the common composite plastic bag materials mentioned above, if they are produced using biodegradable resin raw materials and meet the requirements of environmental protection and safety in relevant national standards, such as biological decomposition rate, heavy metal content, solvent residue, etc., then they meet the environmental protection requirements of Jinan. If it is a non degradable composite plastic bag, it does not meet environmental protection requirements within the prohibited use range specified in Jinan.
