PP袋的定義
Definition of PP bag
pp袋就是以聚丙烯為材料而制作成的塑料袋,其一般采用彩印,膠印工藝,色澤鮮艷 ,一般多做編織袋,另外PP袋是拉伸性的聚丙烯塑料,屬于熱塑性塑料的一種。其、無味、表面光潔透明。容易燃燒,火焰情況為熔融滴落,上黃下藍,離火后煙少,繼續(xù)燃燒,多用于化妝品、食品、玩具、服裝、文具、電子、五金制品等各行業(yè)的包裝。顏色為透明,質量優(yōu)良,韌性好,因其硬脆的材質決定了其只適于包裝不適于承重。PP化學名稱:聚丙烯英文名稱:Polypropylene(簡稱PP)PP為結晶型高聚物,常用塑料中PP輕,密度僅為0.91g/cm3(比水小)。通用塑料中,PP的耐熱性,其熱變形溫度為80-100℃,能在沸水中煮。PP有良好的應力開裂性,有很高的彎曲疲勞壽命,俗稱“百折膠”。PP的綜合性能優(yōu)于PE料。PP產品質輕、韌性好、耐化學性好。PP的缺點:尺寸精度低、剛性不足、耐候性差、易產生“銅害”,它具有后收縮現(xiàn)象,脫模后,易老化、變脆、易變形。日常生活中,常用的保鮮盒就是由PP材料制成。
PP bag is a plastic bag made of polypropylene material, which is generally processed by color printing and offset printing, with bright colors. It is usually made as a woven bag. In addition, PP bag is a stretchable polypropylene plastic, which belongs to a type of thermoplastic. It is non-toxic, odorless, and has a smooth and transparent surface. Easy to burn, with a flame condition of melting droplets, yellow on top and blue on bottom. After leaving the fire, there is less smoke and it continues to burn. It is commonly used for packaging in various industries such as cosmetics, food, toys, clothing, stationery, electronics, and hardware products. The color is transparent, the quality is excellent, and the toughness is good. Due to its hard and brittle material, it is only suitable for packaging and not suitable for load-bearing. PP chemical name: Polypropylene (abbreviated as PP) PP is a crystalline high polymer, commonly used as the lightest plastic with a density of only 0.91g/cm3 (smaller than water). Among general plastics, PP has the best heat resistance, with a heat deformation temperature of 80-100 ℃, and can be boiled in boiling water. PP has good stress cracking resistance and high bending fatigue life, commonly known as "100 fold adhesive". The comprehensive performance of PP is superior to that of PE material. PP products are lightweight, have good toughness, and good chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, and susceptibility to "copper damage". It has a phenomenon of post shrinkage, and after demolding, it is prone to aging, brittleness, and deformation. In daily life, the commonly used fresh-keeping box is made of PP material.
OPP袋的定義
Definition of OPP bag
OPP袋的定義opp是定向拉伸性聚丙烯膜,具有透明度高、較脆等特征,由OPP單片對折后側面封邊并在開口舌頭處粘有自粘封條,使用時裝入產品撕去封條表面的保護皮后將舌頭對折后粘牢即可,使用方便、美觀大方,廣泛使用于服裝、食品、印刷,文具,化妝品,紙張等行業(yè)。
The definition of OPP bag is oriented stretchable polypropylene film, which has the characteristics of high transparency and brittleness. OPP is folded in half and the side is sealed with a self-adhesive seal at the opening tongue. When in use, the protective skin on the surface of the seal is peeled off and the tongue is folded in half and glued firmly. It is convenient to use, beautiful and elegant, and widely used in industries such as clothing, food, printing, stationery, cosmetics, paper, etc.
還可根據(jù)客戶需要印刷各種圖案及打蝴蝶孔、飛機孔。opp膜比普通pp膜具有更高的抗拉伸力、挺度、透明度、光澤度、印刷性能等等。自然也要高些,規(guī)格不同也不一。OPP膜的密封性是傳統(tǒng)膜的一倍以上,從而使其產品的保濕、保鮮性更強,保存時間更長。
We can also print various patterns, butterfly holes, and airplane holes according to customer needs. OPP film has higher tensile strength, stiffness, transparency, glossiness, printing performance, and more than ordinary PP film. The price naturally needs to be higher, and the price varies depending on the specifications. The sealing performance of OPP film is more than twice that of traditional film, making its products more moisturizing, fresh-keeping, and have a longer storage time.
OPP就是定向聚丙烯,O應該主要指生產工藝!OPP:定向,位伸性聚丙烯,是聚丙烯的一種以及雙向聚丙烯(BOPP)OPP主要產品:OPP膠帶:以聚丙烯薄膜為基材,具有高抗拉伸力、質輕、無味、環(huán)保、使用范圍廣等優(yōu)點。OPP瓶:重量輕、成本低、透明度改善、耐熱性佳,適合用于熱灌裝。近年,雙向聚丙烯(OPP)透明瓶成為了PET瓶的代選。
OPP stands for oriented polypropylene, while O mainly refers to the production process! OPP: oriented, stretchable polypropylene, is a type of polypropylene and a two-way polypropylene (BOPP) OPP main products: OPP tape: based on polypropylene film, it has the advantages of high tensile strength, light weight, non-toxic and odorless, environmental protection, and wide range of applications. OPP bottle: lightweight, low cost, improved transparency, excellent heat resistance, suitable for hot filling. In recent years, OPP transparent bottles have become an alternative to PET bottles.
兩種材質的區(qū)別:
The difference between two materials:
1、觸感方面,OPP會顯得比較脆,比較硬,而PP柔軟性更好一些。2、透明度方面,OPP透明度更好,PP的透明度稍差一些,現(xiàn)在有些高透PP的透明度也可以接近OPP。
1. In terms of touch, OPP appears more brittle and hard, while PP has better softness. 2. In terms of transparency, OPP has better transparency, while PP has slightly lower transparency. Nowadays, some high transparency PPs can also have transparency close to OPP.
