PET熱收縮薄膜

PET heat shrinkable film

PET熱收縮薄膜是一種新型熱收縮包裝材料。由于它具有易于回收、、無味、機械性能好、特別是符合環(huán)境保護等特點，在發(fā)達聚酯(PET)已成為取代聚氯乙烯(PVC)熱收縮薄膜的理想替代品。

PET heat shrinkable film is a new type of heat shrinkable packaging material. Because it is easy to recycle, non-toxic, tasteless, and has good mechanical properties, especially in line with environmental protection, polyester (PET) has become an ideal substitute for PVC heat shrinkable film in developed countries.

PVC熱收縮薄膜

PVC聚氯乙烯，外加成分以增強其耐熱性、韌性、延展性等。這種表面膜的上層是漆，中間的主要成分是聚氯乙烯，下層是背涂粘合劑。它是當今世界上深受喜愛、頗為流行并且也被廣泛應(yīng)用的一種合成材料。在可以生產(chǎn)三維表面膜的材料中，PVC是適合的材料。

PVC PVC, with additional ingredients to enhance its heat resistance, toughness, ductility, etc. The upper layer of this surface facial mask is paint, the main component in the middle is PVC, and the lower layer is back coated adhesive. It is a kind of synthetic material which is very popular and widely used in the world today. Among the materials that can produce 3D surface facial mask, PVC is the suitable material.

由于PVC獨特的性能(防雨，耐火，抗靜電，易成型)和PVC低投入高產(chǎn)量的特點，被廣泛地應(yīng)用于建材行業(yè)和包裝行業(yè)，因此，PVC薄膜具有透明度高、光澤度好、收縮率高等特點。

PVC is widely used in building materials and packaging industries due to its unique properties (rainproof, fire-resistant, anti-static, easy molding) and its low input and high output. Therefore, PVC film has the characteristics of high transparency, good glossiness, and high shrinkage.

OPS熱收縮薄膜

OPS（定向聚苯乙烯）熱收縮薄膜是一種符合要求的新型貼體包裝材料，OPS熱收縮薄膜具有強度高、剛性大、形狀穩(wěn)定，且具有良好的光澤度和透明度。加工方便、容易著色、印刷性能好、有的印刷分辨率，對于不斷追求精美印刷的商標來說，完全是一種材質(zhì)的進步。由于OPS薄膜的這種高收縮率和強度，能與各種不同形狀的容器緊密貼合，所以它不僅能印制出精美的圖案，還能滿足各種外形迥異的新穎包裝容器的使用，這種無味，可耐油脂，符合食品衛(wèi)生標準的薄膜可以讓設(shè)計者采用引人注目的顏色，實現(xiàn)360°的標簽設(shè)計，充分發(fā)揮出創(chuàng)造力和想象力，從而使飲料和其它商品在標簽使用中圖案更加生動，突出了在貨架上的形象，產(chǎn)生出一種意想不到的貨柜效應(yīng)。

OPS (Oriented Polystyrene) heat shrinkable film is a new type of body fitted packaging material that meets the environmental requirements. OPS heat shrinkable film has high strength, large rigidity, stable shape, and good glossiness and transparency. Convenient processing, easy coloring, good printing performance, and some printing resolutions are all material improvements for trademarks that constantly pursue exquisite printing. Because this high shrinkage and strength of OPS film can closely fit with containers of different shapes, it can not only print beautiful patterns, but also meet the use of new packaging containers with different shapes. This non-toxic, tasteless, grease resistant film, which meets the food hygiene standards, allows designers to use eye-catching colors to achieve 360 ° label design, giving full play to creativity and imagination, This makes the design of drinks and other goods more vivid in the use of labels, highlights the image on the shelf, and produces an unexpected container effect.

PE熱收縮薄膜

PE heat shrinkable film

PE聚乙烯，它是透明的熱塑性塑料。PE常用的有三大類，即:LDPE、HDPE、LLDPE 三種聚乙烯的單體是一樣，只不過在合成這些聚乙烯時，所采用的工藝條件不一樣，因此才生成三種不同的聚乙烯品種，三種材料的性能有較大的差異。

PE polyethylene, which is a transparent thermoplastic. There are three types of PE commonly used, namely, LDPE, HDPE and LLDPE. The monomers of these three kinds of polyethylene are the same, but the process conditions used to synthesize these polyethylene are different. Therefore, three different polyethylene varieties are generated. The performance of the three materials is greatly different.

PE薄膜是一種韌性很好的材料，不容易用普通的塑料粉碎機粉碎。由于PE膜軟而韌也不易切碎，更何況高速下刀具溫度高，會使LDPE熔化粘附在刀刃上。PE的造?？芍苯映蓷l放入擠出機加料口，靠螺桿的剪切力把PE膜拖進機筒加熱熔融擠出造粒。PE回收的一級料，仍舊可吹膜，用于非食品和藥品包裝，還廣泛用于牛津革和防水布的生產(chǎn)上，前途光明。

PE film is a kind of material with good toughness, which is not easy to be crushed by ordinary plastic crusher. Because the PE film is soft and tough, it is not easy to cut, not to mention the high temperature of the tool at high speed, which will make LDPE melt and adhere to the blade. The PE granulation can be directly put into the extruder feeding port in strips, and the PE film can be pulled into the barrel by the shear force of the screw to heat, melt and extrude for granulation. The first grade materials recycled from PE can still be blown, used for non food and drug packaging, and also widely used in the production of oxford leather and waterproof cloth, with a bright future.

PE熱收縮膜廣泛適用于酒類、易拉罐類、礦泉水類、各種飲料類、布匹等產(chǎn)品的整件集合包裝，該產(chǎn)品柔韌性好,抗撞擊、抗撕裂性強，不易破損、不怕潮、收縮率大。

PE heat shrinkable film is widely applied to the whole package of liquor, pop can, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact and tear resistance, is not easy to damage, is not afraid of moisture, and has a large shrinkage rate.
