袋子是什么材質(zhì)的?符合濟(jì)南的要求嗎?

來源:http://m.treacyeller.com/ 日期:2025-04-14

濟(jì)南的復(fù)合塑料袋通常由多種材質(zhì)復(fù)合而成,常見的有以下幾種:

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

BOPP/CPP 復(fù)合袋:由雙向拉伸聚丙烯薄膜(BOPP)和流延聚丙烯薄膜(CPP)復(fù)合而成。這種復(fù)合袋防潮能力強(qiáng),韌性好,有較強(qiáng)的拉力,耐水耐油性能強(qiáng),透明度高,無味,但耐寒、耐熱性能較差,主要應(yīng)用在熟食品、茶葉、油性食物以及餅干、糖果、方便面等干燥食品包裝。

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 復(fù)合袋:由雙向拉伸尼龍 6 薄膜(BOPA6)和低密度聚乙烯薄膜(LDPE)復(fù)合而成。具有耐高溫、無味、防潮、耐油的特點(diǎn),不過透明度很差,主要應(yīng)用在熟食品、速凍食品等包裝,可以加熱、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 復(fù)合袋:由聚對(duì)苯二甲酸乙二酯薄膜(PET)和聚乙烯薄膜(PE)復(fù)合而成。防氧化性能好,防潮,耐寒,透明度較高,無味,應(yīng)用在各種充氣食品包裝,服裝、針織品、日常生活用品包裝,也可用作購(gòu)物袋、保鮮袋、禮品袋等。

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.

純鋁袋和鍍鋁袋:包括紙鋁復(fù)合袋等。如 opp/al/pe、pet/al/pe 等純鋁復(fù)合袋,以及 pet/vmpet/pe、vmpet/cpp 等鍍鋁復(fù)合袋,具有良好的阻隔性、遮光性、保香性等,可用于對(duì)包裝要求較高的產(chǎn)品,如一些高檔食品、藥品等的包裝。

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.

濟(jì)南對(duì)塑料袋的使用有明確的要求,根據(jù)《濟(jì)南市進(jìn)一步加強(qiáng)塑料污染治理實(shí)施方案》,到 2020 年底,城市建成區(qū)的、、藥店、書店等場(chǎng)所及餐飲打包外賣服務(wù)和各類展會(huì)活動(dòng),禁止使用不可降解塑料袋;到 2025 年底,城市建成區(qū)集貿(mào)市場(chǎng)禁止使用不可降解塑料袋。上述常見的復(fù)合塑料袋材質(zhì)中,如果是采用可降解的樹脂原料生產(chǎn),并且符合相關(guān)標(biāo)準(zhǔn)中關(guān)于、等方面的要求,如在生物分解率、重金屬含量、溶劑殘留量等指標(biāo)上達(dá)標(biāo),那么就是符合濟(jì)南要求的。如果是不可降解的復(fù)合塑料袋,在濟(jì)南規(guī)定的禁止使用范圍內(nèi)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.
