POF与PE、PVC收缩膜物理性能优劣比较
POF与PE、PVC收缩膜物理性能优劣比较
Comparison of the physical properties of POF with PE and PVC
1.成本 POF比重0.92,厚度最薄0.012mm,实际单位成本较低. PE比重0.92,厚度最薄0.03以上,实际单位成本较高. PVC比重1.4,厚度最薄0.02mm,实际单位成本较高.
1. the proportion of 1. cost is 0.92, the thickness is 0.012mm, the actual unit cost is low. The proportion of PE is 0.92, the thickness is thinner than 0.03, the actual unit cost is higher. The proportion of PVC is 1.4, the thickness is 0.02mm, the actual unit cost is higher.
2.物性 POF薄而韧,厚度均匀,防潮性佳,质地柔软.抗拉强度高,耐撕裂强度大,收缩率可调.因LLDPE存在,耐揉搓性更好. PE厚而韧,厚度均匀,防潮性佳,质地柔软.耐撕裂强度低于POF,但远高于PVC,收缩率可调性差.耐揉搓性不如POF. PVC厚而脆,厚薄不均,防潮性差,质地硬脆.强度低,收缩率低,耐揉搓性差.
2. POF is thin and toughened, the thickness is good, the texture is soft, the tensile strength is high, the tear strength is high, the shrinkage is adjustable. Because of the existence of LLDPE, the rubbing resistance is better. The PE is thick and toughened, the thickness is uniform, the moisture resistance is good and the texture is soft. The tear strength is lower than POF, but it is far higher than PVC, and the shrinkage is poor. The rubbing resistance is not as thick and crisp as POF. PVC. Uneven thickness, poor moisture resistance, hard and brittle texture, low strength, low shrinkage, poor rubbing resistance.
3.耐寒等物性 POF耐寒性极优,-50℃不硬不脆,不易破裂,可用于冷冻食品包装.收缩包装后, -50℃--95℃被包装物长期存放,稳定不变.有静电和防雾处理,不易污染灰尘,可保持产品清洁亮丽.PE 耐寒性特优,冬天或冷冻后,不发硬,不脆化,因此运输不易破裂.有静电消除处理,不易染尘,可保持产品清洁. PVC耐寒性极劣,冬天或冷冻后会发生脆化,因此运输中易破裂.收缩包装愈久,收缩会愈紧,被包装物变形.无静电消除处理,易沾染灰尘,令产品污染模糊.
3. cold resistance and other physical property POF cold resistance is very good, -50 C is not hard and brittle, not easy to break, can be used in frozen food packaging. After contraction packaging, -50 C --95 C is stored for a long time, stable and stable. Static and anti fogging treatment, not easy to pollute the dust, and keep the product clean and bright.PE cold tolerance, in winter or after the freezing, not hard, not embrittlement, because the cold, not embrittlement, because The transportation is not easy to break. It has electrostatic elimination treatment, it is not easy to dye the dust, it can keep the product clean. The cold resistance of PVC is very bad, it will be brittle in winter or after the freezing, so it is easy to break in transportation. The longer the contraction package is, the more tight the contraction will be, the more the packaging is deformed. It is easy to stain the dust and make the product pollute.
4.加工性能 POF加工过程不产生水分也不会粘着于封棒上,保养及作业容易.高韧性,平滑性及抗揉搓性使其适用于高速生产线自动包装. PE加工过程不产生水分,也不粘于封棒上,保养及作业容易.高韧,低揉搓性,可用于较高速生产线自动包装. PVC加工过程会产生挥发分,易造成机械损坏,又易粘着于封棒上,作业不方便,保养困难.
4. processing performance POF processing process does not produce water or sticky on the sealing rod, easy maintenance and operation. High toughness, smoothness and rubbing resistance make it suitable for automatic packaging of high speed production line. PE process does not produce water, is not sticky on sealing rod, easy maintenance and operation. High Toughening, low kneading, can be used in higher speed production line from the high speed production line. Dynamic packaging. PVC process will produce volatile, easy to cause mechanical damage, and easy to stick on the sealing rod, the operation is inconvenient, maintenance is difficult.
5.安全性 POF收缩包装后,封口处四角柔软,不会割伤人手,也耐揉搓. PE收缩包装后,封口四角柔软,不会割伤人手. PVC收缩包装后,封口处四角硬且尖锐,易割伤流血.
5. safety POF shrink packaging, four corners of the seal is soft, will not cut the hand, and also resistant to rubbing. After the contraction of PE, the sealing four angles are soft and will not cut the hands. After PVC contraction packaging, the four corners of the seal are hard and sharp, easily cut and bleeding.
6.环保卫生 POF无毒性，加工时不产生有毒气味，符合美国FDA和USDA标准。 PE无毒性,加工时不产生有毒气体,符合美国FDA和USDA标准. PVC有毒性,加工会产生臭味,有毒气体,逐渐禁用.
6. environmental sanitation POF is non-toxic and does not produce toxic odor when processing. It meets the FDA and USDA standards of the United States. PE is non-toxic. It does not produce toxic gas when it is processed. It is in line with the FDA and USDA standards of the United States. PVC is toxic. Processing produces odors and toxic gases are gradually prohibited.
