在濟南，無論是商超購物、餐飲打包還是工業包裝，塑料袋都是不可或缺的工具。面對市場上琳瑯滿目的產品，如何選擇既經濟又實用的塑料袋？本文將從材質、規格、用途等多個維度，為您提供通俗易懂的選購建議。

In Jinan, plastic bags are an indispensable tool for shopping in supermarkets, packaging in restaurants, and industrial packaging. How to choose an economical and practical plastic bag when facing the dazzling array of products in the market? This article will provide you with easy to understand purchasing suggestions from multiple dimensions such as material, specifications, and usage.

一、材質選擇的核心邏輯

1、 The core logic of material selection

塑料袋的性能主要取決于原材料類型：

The performance of plastic bags mainly depends on the type of raw materials:

高密度聚乙烯（HDPE）

High density polyethylene (HDPE)

這種材質的塑料袋質地較硬，拉伸強度可達 20MPa 以上，適合裝重物。濟南某檢測機構數據顯示，厚度 0.03mm 的 HDPE 袋可承重 5kg，常用于大米、面粉等商品包裝。

This type of plastic bag has a harder texture and a tensile strength of over 20MPa, making it suitable for carrying heavy objects. According to data from a testing agency in Jinan, HDPE bags with a thickness of 0.03mm can bear up to 5kg and are commonly used for packaging rice, flour, and other goods in supermarkets.

低密度聚乙烯（LDPE）

Low density polyethylene (LDPE)

質地柔軟且延展性好，斷裂伸長率超過 500%，適合日常輕量物品。濟南早市常見的 0.02mm 超薄袋多為此材質，每只成本約 0.03 元，但承重僅 1.5kg，易破損。

The texture is soft and has good ductility, with a fracture elongation of over 500%, suitable for daily lightweight items. The commonly seen 0.02mm ultra-thin bags in Jinan morning market are mostly made of this material, with a cost of about 0.03 yuan per bag, but they can only bear 1.5kg and are easily damaged.

可降解材料

degradable material

采用 PBAT/PLA 復合材質的袋，在濟南夏季高溫高濕環境下，6 個月降解率可達 90%。某組織測試顯示，這種袋子的承重能力與普通 LDPE 相當，但成本高出 40%。

The environmentally friendly bag made of PBAT/PLA composite material can achieve a degradation rate of 90% in 6 months in the high temperature and high humidity environment of Jinan in summer. According to a test conducted by an environmental organization, the load-bearing capacity of this type of bag is equivalent to that of ordinary LDPE, but the cost is 40% higher.

二、場景化選購策略

2、 Scenario based purchasing strategy

1. 商超零售

1. Supermarket retail

優先選擇帶提手設計的背心袋，某消費者調研顯示，提手承重超過 3kg 時，使用滿意度提升 42%。

Priority should be given to vest bags with handle designs. A consumer survey showed that when the handle weighs more than 3kg, satisfaction with use increases by 42%.

考慮印刷需求，濟南某印刷廠數據顯示，單色印刷成本約 0.01 元 / 個，四色印刷增加 0.03 元。

Considering printing demand, data from a printing factory in Jinan shows that the cost of monochrome printing is about 0.01 yuan per unit, while four-color printing increases by 0.03 yuan.

2. 餐飲外賣

2. Catering takeout

選用食品級 PE 材質，某檢測標準要求，直接接觸食品的塑料袋需通過 GB 4806.7 認證。

Using food grade PE material, a certain testing standard requires that plastic bags that come into direct contact with food must pass GB 4806.7 certification.

帶熱封條的包裝袋，某餐飲店實測，這種設計使湯汁滲漏率下降 65%。

Recommend packaging bags with heat seals. A certain restaurant has tested that this design reduces the leakage rate of soup by 65%.

3. 工業包裝

3. Industrial packaging

選擇防靜電材質，某電子廠經驗顯示，使用防靜電袋可使產品不良率降低 22%。

Choosing anti-static materials, experience from an electronics factory shows that using anti-static bags can reduce product defect rates by 22%.

厚度需≥0.08mm，某物流公司測試表明，0.1mm 厚袋子在運輸顛簸中的破損率僅為 0.5%。

The thickness needs to be ≥ 0.08mm. A logistics company's test shows that the damage rate of 0.1mm thick bags during transportation bumps is only 0.5%.
