定做塑料袋有很多種樣式,規(guī)格分為長度、寬度、測寬度、厚度四個數(shù)據(jù);常見的材料有壓聚乙烯材料、聚乙烯材料、乙烯材料等,下面具體介紹一下“定做塑料袋的基本常識及材料”。
There are many styles of customized plastic bags. The specifications are divided into four data: length, width, measured width and thickness; Common materials include pressure polyethylene materials, polyethylene materials, ethylene materials, etc. the following is a specific introduction to "basic knowledge and materials of customized plastic bags".
 
一、定做塑料袋的基本常識
 
1、 Basic knowledge of customized plastic bags
 
1、塑料袋樣式塑料袋有很多種樣式,生產(chǎn)的難度、工序、效率是不一樣的,所以也是不同的,例如背心袋、平口袋、孔式袋是比較簡單的,那么就便宜一點,還有一些特殊樣式的穿繩袋、手提袋、異形袋需要手工制作,難度較高,那么就高一點。
 
1. There are many styles of plastic bags. The production difficulty, process and efficiency are different, so the price is also different. For example, vest bags, flat bags and hole bags are relatively simple, so the price is cheaper. There are also some special styles of rope bags, handbags and special-shaped bags that need to be made by hand, which are more difficult, so the price is higher.
 
2、塑料袋材料有新料、回收料、添充料,各種材料不同生產(chǎn)出來的塑料袋質(zhì)量相差很多,所以也有很大的差別。
 
2. Plastic bag materials include new materials, recycled materials and filling materials. The quality of plastic bags produced by different materials varies a lot, so the price also varies greatly.
 
3、塑料袋規(guī)格塑料袋規(guī)格分為長度、寬度、測寬度、厚度四個數(shù)據(jù),每項的不同造成的也就不同,所以客戶不能以大概來
 
3. Plastic bag specification the plastic bag specification is divided into four data: length, width, measured width and thickness. The price of each item is different, so the customer can't estimate it roughly
 
二、塑料袋定做的材料有哪些
 
2、 What are the customized materials for plastic bags
 
1、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。
 
1. Pressed polyethylene material: it has good tensile force and hardness, and bright color. It is mainly used to make supermarket vest bags, custom shopping bags, etc.
 
2、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。
 
2. Polyethylene material: it is relatively soft, smooth surface, strong flexibility and brighter color than low-pressure materials. It is used for most clothing bags and gift bags. The grade of customized plastic bags is generally higher than that of low-pressure film materials.
 
3、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(wěn)定劑、抗老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。
 
3, ethylene material: its own high strength, corrosion resistance, non flammability, but in order to enhance plastic bags into heat resistance, toughness, ductility, etc., in the production process has added plasticizers, stabilizers, anti-aging agents and other toxic auxiliary materials. Therefore, it is not suitable for food packaging. It is commonly used in cosmetics packaging and box packaging.

4、烯材料:其密度小,強度剛度,硬度耐熱性均優(yōu)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。
 
4. Alkene material: its density, strength, stiffness, hardness and heat resistance are better than low-pressure materials, but it is easy to crack, easy to aging and not wear-resistant. Therefore, it is mostly used in clothing packaging and textile packaging.
