塑料包装材料的性能特点 The performance characteristics of plastic packaging materials 优点列举 物理机械性能好,阻隔性好,优良的耐化学药品性,良好的加工适应性。 Advantages are good physical and mechanical performance, good barrier property, excellent chemical resistance, good processing adaptability. 缺点列举 强度不如钢铁,耐热度不及金属和玻璃,部分塑料含有毒单体 ,易带静电 ,废弃物的处理困难。 Shortcomings listed steel is better than strength, heat resistance than metal and glass, part of the plastic containing toxic monomer, easy with static electricity, waste processing difficulties. 1、低密度聚乙烯(LDPE、LLDPE) 1, low density polyethylene (LDPE, LLDPE), 聚乙烯为白色蜡状固体,呈半透明,几乎是无味无毒。聚乙烯大分子链的柔顺性好,很容易结晶,常温下聚乙烯由部分结晶和部分处于高弹态的无定形体构成。 Polyethylene is white waxy solid, translucent, is almost tasteless non-toxic. Polyethylene macromolecular chain of good flexibility, easy to crystallization, temperature of polyethylene by fractional crystallization and part of amorphous body in a high elastic state. LDPE LDPE 性能特点 The performance characteristics of 低密度聚乙烯的加工性能好,有较好的透明性,但气密性差,抗张强度较低,且耐热温度不高,耐化学药品性、耐溶剂性也不及高密度聚乙烯,且容易吸收油脂溶胀,使制品发粘。 Low density polyethylene processing performance is good, has the good transparency, but poor air tightness, low tensile strength, and hot temperature is not high, chemical resistance, solvent resistance is not as good as high density polyethylene, and easy to absorb oil swelling, make the products be sticky. 适用范围 Scope of application 吹塑瓶、挤压软管用于调味品、药品等包装;瓶盖、瓶塞等容器附件;各种包装薄膜、容器和泡沫塑料缓冲材料。 Bottle blow molding, extrusion hose used for seasoning, pharmaceuticals packaging; Bottle caps, bottle stopper and other containers in attachment; All kinds of packaging film, containers and plastic foam buffer materials. LLDPE LLDPE 性能特点 The performance characteristics of 抗冲击强度、耐应力开裂性与高密度聚乙烯相近,而透明度、硬度和加工性能则在高密度和低密度聚乙烯之间。伸长率和耐穿刺性是各种聚乙烯中最好的。 Impact strength, stress cracking resistance, and high density polyethylene, and transparency, hardness and processing performance is between the high density and low density polyethylene. Elongation and durable thorn is one of the best in all kinds of polyethylene. 适用性 applicability 特别适宜作包装薄膜,其厚度可比低密度聚乙烯减薄20%,是一种很有发展前途的塑料包装材料。 Is suitable for packaging film, its thickness than the low density polyethylene thinned 20%, is a kind of very promising plastic packaging materials. 2、高密度聚乙烯(HDPE)high density polyethylene 2, high density polyethylene (HDPE) high density polyethylene 性能特点 The performance characteristics of 强度、耐热性好,最高温度可达120℃,透明性、弹性和加工性能较差,阻气性差,光泽度低,印刷前需表面处理。 Strength, good heat resistance, the highest temperature can reach 120 ℃, transparency, flexibility and processing performance is poorer, carbamate resistance is poor, low gloss, surface treatment before the printing. 适用范围 Scope of application 集装箱、托盘,大型桶用于鲜奶、化工产品等周转包装,瓶用酸奶、洗涤液漂白剂包装,瓶盖、瓶塞等容器附件。 Container, pallet, large barrels used for milk, chemical products such as plastic packaging, bottle packed in yogurt, detergents, bleach, bottle caps, bottle stopper and other containers in attachment. 3、发泡聚乙烯—EPE(俗称珍珠棉) 3, foaming polyethylene - EPE (commonly known as pearl cotton) 分为片材、板材、管材、棒材及其分割切片造型等。 Divided into sheet, plate, pipe, bar and segmentation section shape and so on. 适用范围 Scope of application 广泛适用包装任何形状货品,特别是电子产品如:电脑、电视、音响、音箱等各类电器的抗静电缓冲包装。珍珠棉属于环保型,特点是弹性好、韧性强。也可造救生衣、浮板、旅行袋,帽等。 Widely used packaging any shape of goods, especially the electronic products such as: computer, TV, acoustics, speakers and other kinds of antistatic of cushion packaging. Pearl cotton belong to environmental protection, is characterized by good elasticity, strong toughness. Can also be made jackets, floating plate, travel bag, hats, etc. 4、聚丙烯(PP)polypropylene 4, polypropylene (PP) polypropylene 性能特点 The performance characteristics of 聚丙烯是通用塑料中最轻的一种,其耐热性是通用塑料中最高的,可在100℃~120℃长期使用。结晶度高,抗张强度和硬度均优于聚乙烯,防潮性、抗水性和防止异味透过性较好,可以热封合。极好的耐弯曲疲劳强度,能耐80℃以下酸、碱、盐液及大多数有机溶剂如聚丙烯包装盒就利用了这一特性。 Polypropylene is one of the most light in general plastic, its heat resistance is common among the highest in the plastic, can be in 100 ℃ ~ 100 ℃ for long-term use. High crystallinity and tensile strength and hardness are better than polyethylene, moisture resistance, water resistance and prevent odor has good permeability, can heat sealing. Excellent resistance to bending fatigue strength, under 80 ℃ acid, alkali, salt solution and most organic solvents such as polypropylene packing box to use this feature. 耐寒性、耐老化性差,气密性不良,不适宜在低温下使用,且容易受光、氧的影响。粘接或印刷前必须经过表面处理。 Bad cold resistance, aging resistance, air tightness, not suitable for use in low temperature, and easily affected by light and oxygen. Adhesive or must go through surface treatment before printing. 适用范围 Scope of application 广泛用于制作食品、化工产品、化妆品、食品饮料、啤酒等周转箱,吹塑瓶用于洗发液、化妆品等包装,螺纹瓶盖或带铰链包装、编织袋以及包装用薄膜、打包带和泡沫塑料缓冲材料等。 Widely used in the production of food, chemical products, cosmetics, food and beverage, beer, such as turnover box, blow molding bottles for shampoo, cosmetic packaging, threaded cap or hinged, woven bag packaging and packaging film, packaging tapes and foam buffer material, etc.
