高效利用：
K树脂密度低于其他透明材料是降低成本的一大特点。同时K树脂具有挤塑量高、注塑与热成型作业周期短、热成型性优异等特点，令高生产率得以保证。
应用K树脂制成的零部件可进行装饰、印刷、粘合或焊接等各种后加工工序和涂装。用K树脂制成医药和保健的部件可作高能量辐射（ν射线或电子束）或环氧乙烷进行消毒。
可应当可以反覆多次回收利用，在性能上和加工能上仅有极微小的变化，比ABS和AS要好回收 。
加工性能：
①.吸湿少，加工前不需干燥。
②.加工温度较宽，一般在160--260℃之间，流动性好，容易加工。
③.不结晶，收缩率低，不易变形、翘曲等。
④.二次加工。
A.印刷性能：多数牌号的k胶可直接印刷，对较难印刷的可采用电晕放电处理、等离子处理或火焰处理后再印刷。
B.粘合：可以采用溶剂粘合,例如:醋酸乙酯、二氯甲烷;也可以用超声波焊接。
主要应用：
1、高性价比和透明性：应用K树脂包装具有优异的尺寸稳定性
K树脂食品包装（如杯子、托盘和食品盒等）不仅外观醒目而且坚固耐用。
K树脂不仅透明，而且具备很高的抗冲击强度，可以满足食品工业的特殊要求。这种材料的优异特性对于要求高度尺寸稳定性的挤塑和热成型食品包装（如饮料杯、沙拉盘、熟食盘和带盖与薄膜铰链的午餐盒等）都是至关重要的。
透明片材的吸塑产品早已广泛应用于医疗器械、化妆品和消费性电子产品的包装上。而利用K树脂与普通聚苯乙烯（GPPS）之间优良的混合性来制造的透明包装片材，能使吸塑产品更美观和更具成本效益。
Efficient use: K resin density is lower than other transparent materials is a major feature of cost reduction. At the same time, K resin has the characteristics of high extrusion capacity, short injection and thermoforming cycle, excellent thermoforming, so that high productivity can be guaranteed. The parts made of K resin can be used for decoration, printing, bonding or welding and other post-processing processes and coating. Medical and health components made from K resin can be sterilized by high-energy radiation (oxirane rays or electron beams) or oxirane. It should be able to be recycled many times, with minimal changes in performance and processing power, and is better recycled than ABS and AS. Processing Properties: 1. Less moisture absorption, no drying before processing. 2. Processing temperature is wide, generally between 160-260 ° C, good fluidity, easy to process. 3. No crystallization, low shrinkage, not easy to deformation, warpage, etc. . Four. Secondary processing. A. Printing performance: most brands of K can be printed directly, the more difficult to print can be used corona discharge treatment, plasma treatment or flame treatment after printing. B. Bonding: you can use solvent bonding, such as ethyl acetate, dichloromethane, or you can use Ultrasonic welding.Application: 1, high performance-price ratio and transparency: application k resin packaging has excellent dimensional stability K resin food packaging (such as cups, trays and food boxes, etc.) not only eye-catching appearance and durable. K resin not only transparent, but also has high impact strength, can meet the special requirements of the food industry. The superior properties of this material are critical for extruded and thermoformed food packaging that requires a high degree of dimensional stability, such as beverage cups, Salad Bowl, deli trays and lunch boxes with lids and membrane hinges. Transparent sheet blister products have been widely used in medical devices, cosmetics and consumer electronics packaging. The transparent packaging sheet made of k resin and ordinary polystyrene (GPPS) can make the blister products more beautiful and more cost-effective.
