瘦身PE保鲜膜之所以具备上述的优势，因为普通的保鲜膜以下几点工作做的不到位：
Slimming PE fresh-keeping film has the advantages above, because the ordinary plastic film below work is not in place:
一方面是因为PE保鲜膜使用的原材料是结晶材料，结晶比较简单，于是后期制成的PE薄膜透明度、柔韧性、回缩性都不好；正是因为普通保鲜膜的结晶性决定了不能具有比较好的防雾效果；
On the one hand, because the raw material of PE fresh-keeping film is crystalline material, the crystallization is relatively simple, so the later PE film transparency, flexibility and retraction are not good; it is because of the crystallization of ordinary fresh-keeping film determines that it can not have better antifogging effect;
二，PE材料本身黏性几乎为零，黏性不是很好，于是浅盘底面黏着性会不好，后期极易出现散盘现象。
Two, PE viscous material itself is almost zero, the viscosity is not very good, so the tray bottom adhesion is not good, later appear easily scattered disc phenomenon.
瘦身PE保鲜膜和普通PE保鲜膜比较之后，大家注意从加工方式、基材、增勃剂和防雾剂种类的选择及用量的确定、柔韧度及回缩性改进等方面入手，高透明柔软PE保鲜膜配方设计时应该注意：
After comparing the PE fresh-keeping film with the ordinary PE fresh-keeping film, attention should be paid to the selection of processing methods, substrate, increasing agent and antifogging agent, the determination of dosage, the flexibility and the improvement of shrinkage, and so on. The design of high transparent soft PE preservative film should be noticed:
（1）PE保鲜膜无毒性，PE保鲜膜透水性、透气性很好，大家可以放心进行食品保鲜使用；
(1) PE preservative film has no toxicity, and PE film has good water permeability and air permeability, so we can safely use the fresh food;
（2）PE保鲜膜本身黏性接近为零，大家可以添加一定量的增乳剂进行后期的浅盘包装；
(2) PE film itself viscosity is close to zero, we can increase the emulsion by adding a certain amount of post packaging tray;
（3）为降低PE保鲜膜的结晶度，增加柔韧性、收缩性，大家可以添加一定比例的柔韧剂；
(3) in order to reduce the crystallinity of PE film, increase flexibility and shrinkage, you can add a certain proportion of flexible agent;
（4）PE保鲜膜无防雾效果，需添加适量的防雾剂。
(4) PE preservative film has no antifogging effect, and proper antifogging agent should be added.
