一般客户定做塑料袋的品种多是购物袋、服装手提袋、背心袋、食品袋等，虽然统称为塑料袋，但是它们的材料质量是不同的。接下来先详细为大家介绍济南塑料袋材料的差异：

The variety of custom-made plastic bags for general customers is mostly supermarket shopping bags, clothing tote bags, vest bags, food bags, etc. Although collectively referred to as plastic bags, their material quality is different. Next, let's introduce in detail the differences in plastic bag materials in Jinan:

种是低压聚乙烯材料：它有较好的拉力和硬度，而且色泽光亮，主要用于制作背心袋，定做购物袋等。

The first type is low-pressure polyethylene material: it has good tensile strength and hardness, and a bright color, mainly used for making supermarket vest bags, customized shopping bags, and so on.

第二种是高压聚乙烯材料：它比较柔软、表面光滑、、柔韧性强、色泽比低压料光亮，是大多服装袋、礼品袋的，其定做塑料袋的档次一般要高于低压膜材料。

The second type is high-pressure polyethylene material: it is relatively soft, with a smooth surface, strong flexibility, and a brighter color than low-pressure materials. It is the first choice for most clothing bags and gift bags, and the grade of customized plastic bags is generally higher than low-pressure film materials.

第三种是聚氯乙烯材料：它本身具有高强度、耐腐蚀、不易燃性，但是为了增强塑料袋放入耐热性，韧性，延展性等，在制作过程中增加了增塑剂、稳定剂、抗老化剂等一些有毒辅助材料。因此不适合食品包装，常用于化妆品包装、箱包装。

The third is PVC material: it has high strength, corrosion resistance and non flammability, but in order to enhance the heat resistance, toughness and ductility of plastic bags, plasticizers, stabilizers, anti-aging agents and other toxic auxiliary materials are added in the production process. Therefore, it is not suitable for food packaging and is commonly used for cosmetic packaging and box packaging.

第四种是聚丙烯材料：其密度小，强度刚度，硬度耐热性均优于低压料，但是易破裂、易老化、不耐磨，因此多用于服装包装，纺织品包装。

The fourth type is polypropylene material: its density is small, strength and stiffness, hardness and heat resistance are better than low-pressure materials, but it is prone to cracking, aging, and wear resistance, so it is often used for clothing packaging and textile packaging.

说完了材料的差异，在来和大家说说塑料袋的定做过程。

After discussing the differences in materials, let's talk about the customization process of plastic bags.

1、提供塑料袋的具体尺寸

1. Provide specific dimensions of plastic bags

2、确定塑料袋的用料

2. Determine the material used for plastic bags

3、选择塑料袋的样式类型

3. Choose the style type of plastic bag

4、LOGO矢量图文如果没有可以设计制作,不收设计费,版费是要收的。

4. If the logo vector graphics and text are not available, they can be designed and produced for free, and there is no design fee charged. The edition fee is chargeable.

5、塑料袋制作准备,买料、吹膜、印刷、分切、包装、交货。

5. Preparation for plastic bag production, purchasing materials, blowing film, printing, cutting, packaging, and delivery.

7、塑料袋制作周期:正常情况下设计、制版要 6 天,制袋 7 天,成品出来估计要 13天左右。

7. Plastic bag production cycle: Normally, it takes 6 days for design and plate making, 7 days for bag making, and an estimated 13 days for finished products to be produced.

8、塑料袋成品数量问题:因为吹膜、印刷要试机器,所以出来的袋子可能比订购数量多点也可能少点,一般是按照实际数量付款。

8. The quantity of finished plastic bags: because film blowing and printing need to test the machine, the bags may be more or less than the ordered quantity. Generally, the payment is based on the actual quantity.
