塑料袋訂做材質(zhì)與型號的選擇

來源:http://wujikeji.com/ 日期:2023-05-05

塑料袋是一種定制化生產(chǎn)方式,可以根據(jù)客戶要求的尺寸、材質(zhì)、顏色、印刷圖案等要求進行生產(chǎn)。濟南塑料袋訂做時,需要根據(jù)實際需要選擇不同材質(zhì)和型號,以下是常用的幾種材質(zhì)和型號的介紹:
Plastic bags are a customized production method that can be produced according to customer requirements such as size, material, color, and printing patterns. When customizing plastic bags in Jinan, different materials and models need to be selected according to actual needs. The following is an introduction to several commonly used materials and models:
聚乙烯(PE)塑料袋:聚乙烯是常用的塑料袋材質(zhì)之一,分為高密度聚乙烯(HDPE)和低密度聚乙烯(LDPE)兩種。HDPE塑料袋比較堅硬,適合裝重物,而LDPE塑料袋比較柔軟,適合裝輕物。PE塑料袋透明度高,防潮、防水、耐磨、耐酸堿等特點,廣泛用于食品、醫(yī)藥、化工等行業(yè)。
Polyethylene (PE) plastic bags: Polyethylene is one of the commonly used plastic bag materials, divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). HDPE plastic bags are relatively hard and suitable for holding heavy objects, while LDPE plastic bags are relatively soft and suitable for holding light objects. PE plastic bags have high transparency, moisture resistance, waterproofing, wear resistance, acid and alkali resistance, and are widely used in industries such as food, medicine, and chemical engineering.

聚丙烯(PP)塑料袋:聚丙烯是另一種常用的塑料袋材質(zhì),比PE塑料袋更堅韌,抗撕裂性好。PP塑料袋有多種類型,如平口袋、封口袋、自封袋、拉鏈袋等,適用于文具、服裝、紡織等行業(yè)。
Polypropylene (PP) plastic bags: Polypropylene is another commonly used plastic bag material, which is stronger and has better tear resistance than PE plastic bags. PP plastic bags come in various types, such as flat pockets, sealed pockets, self sealing bags, zipper bags, etc., suitable for industries such as stationery, clothing, textiles, etc.
聚乳酸(PLA)塑料袋:聚乳酸是一種新型可降解塑料,具有較高的生物降解性,是型的塑料袋。PLA塑料袋適用于食品、、快遞等領(lǐng)域。選擇塑料袋的型號需根據(jù)實際需要選擇不同的規(guī)格型號,如袋子的尺寸、厚度、光澤度等。
Poly (lactic acid) (PLA) plastic bags: PLA is a new type of biodegradable plastic with high biodegradability and is an environmentally friendly plastic bag. PLA plastic bags are suitable for fields such as food, supermarkets, and express delivery. Choosing a plastic bag model requires selecting different specifications based on actual needs, such as bag size, thickness, glossiness, etc.
此外,還需結(jié)合袋子的用途和裝載物品的特點來選擇不同的密封方式、口形、拉力等。所以,在訂做塑料袋時,需根據(jù)實際使用需求選擇合適的材質(zhì)、型號和規(guī)格。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://wujikeji.com咨詢吧!
In addition, it is necessary to choose different sealing methods, mouth shapes, tension, etc. based on the purpose of the bag and the characteristics of the loaded items. So, when customizing plastic bags, it is necessary to choose appropriate materials, models, and specifications based on actual usage needs.
