一般客戶定做塑料袋的品種多是購物袋、服裝手提袋、背心袋、食品袋等，雖然統稱為塑料袋，但是它們的材料質量是不同的。接下來先詳細為大家介紹濟南塑料袋材料的差異：

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:

種是低壓聚乙烯材料：它有較好的拉力和硬度，而且色澤光亮，主要用于制作背心袋，定做購物袋等。

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.

第二種是高壓聚乙烯材料：它比較柔軟、表面光滑、、柔韌性強、色澤比低壓料光亮，是大多服裝袋、禮品袋的，其定做塑料袋的檔次一般要高于低壓膜材料。

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.

第三種是聚氯乙烯材料：它本身具有高強度、耐腐蝕、不易燃性，但是為了增強塑料袋放入耐熱性，韌性，延展性等，在制作過程中增加了增塑劑、穩定劑、抗老化劑等一些有毒輔助材料。因此不適合食品包裝，常用于化妝品包裝、箱包裝。

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.

第四種是聚丙烯材料：其密度小，強度剛度，硬度耐熱性均優于低壓料，但是易破裂、易老化、不耐磨，因此多用于服裝包裝，紡織品包裝。

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.

說完了材料的差異，在來和大家說說塑料袋的定做過程。

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

1、提供塑料袋的具體尺寸

1. Provide specific dimensions of plastic bags

2、確定塑料袋的用料

2. Determine the material used for plastic bags

3、選擇塑料袋的樣式類型

3. Choose the style type of plastic bag

4、LOGO矢量圖文如果沒有可以設計制作,不收設計費,版費是要收的。

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、塑料袋制作準備,買料、吹膜、印刷、分切、包裝、交貨。

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

7、塑料袋制作周期:正常情況下設計、制版要 6 天,制袋 7 天,成品出來估計要 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、塑料袋成品數量問題:因為吹膜、印刷要試機器,所以出來的袋子可能比訂購數量多點也可能少點,一般是按照實際數量付款。

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.
