Hello everyone, today the topic of sharing is the selection of body packaging film (body film) . Skin packaging film has been widely used due to the development of China's export manufacturing industry and the popularity of skin packaging machines (skin packaging machines). Body-packing is a popular high-end inner packaging method in the world. Although the cost of skinny packaging is slightly higher than other packaging methods, foreign merchants tend to be more interested in skinny packaging. We can see the clue from this. There are not many types of skin-packing films (body-packing films) on the market. How can we choose the appropriate body-packing film to ensure that the ideal skin-packing effect is obtained at a lower cost? Today, the editor of Fengyuan Information Center will use nearly 20 years of personal packaging experience to tell you the principles and techniques.

First, understand the types of skin-packaging films and their advantages and disadvantages.

In terms of materials, there are mainly PVC, PE, PET, EVA, sarin (sand shower) body film, etc. There are specific types of skin-packaging films with and without adhesiveness.

PVC is a semi-rigid body-fitting film , which has the advantages of high transparency and low cost. It can be used to package larger products with thinner films. The disadvantage is that it is not environmentally friendly, and it is easier in low temperature environments (below 4 degrees, especially in the north). Brittleness may cause package breakage and product scattering. Therefore, for general packaging screws, standard parts, small hardware accessories, etc., try not to use PVC skin packaging film (unless low price is the first consideration).

Non-sticky (without adhesive) PE body packaging film can be used for vacuum skin packaging (vacuum protective packaging) of PCB circuit boards (circuit boards).

Adhesive (with adhesive) environmentally friendly PE skin packaging film, has a wide range of uses, because it is affordable, food-grade, environmentally friendly, non-toxic, high transparency, vacuum plastic skin molding effect is good, can withstand low temperature (low temperature will not Embrittlement), strong aging resistance, can play the role of long-term continuous vacuum tightening protection packaging. Therefore, it is widely used in packaging lighting fittings, automobile and motorcycle accessories (radiators, brake pads, bearings, etc.), ferrite cores, locks, crafts, hardware accessories, drills, saw blades and other hardware tools, stationery, toys , Mold hardware, medical supplies and other products.

PET贴体膜，透明度极高，深拉伸热成型性能非常高，享有”吸不破的贴体包装膜”美誉，主要用于包装大件、重件、形状不规则的产品。沙林膜透明度高，拉伸性能高，但是价格相对较高，适合包装价值较高的产品。

沙林膜（杜邦沙林贴体包装膜），透明度非常高，堪比水晶，是包装高档产品和高难度产品的首选。其他贴体膜包装达不到要求的情况下，沙林膜都可以达到您的包装要求。不带粘性沙林膜，需要配套使用带胶的专用透气纸板（成本会比较高）。建议采用带粘性的沙林膜，可以采用普通纸板包装，减低成本，减少工序复杂度。这是非常重要的贴体包装膜（贴体膜）选用诀窍之一。

其次，要根据产品的实际包装需求来选用。

第一类需求：仅仅是为了保护产品，外观和卖相不是那么看重，或者是用于包装半成品，为了保护本成品进入下一道制造工序。这样的产品有：线路板，汽车水箱散热器，铁氧体磁芯，螺丝工具包（修理包），铍铜（不锈钢）卷材，模具配件等。这样可以选择PVC贴体膜、PE贴体包装膜等价格较低的膜类。

第二类需求：要求卖相要好，视觉效果要好，比如高价值的五金制品，装饰品，玩具，文具，工艺品，锯片、钻头等工具五金，等等。可以选择PE贴体膜，或透明度延伸性更佳的沙林膜（杜邦沙淋膜）、PET贴体包装膜等。当然，这类膜的价格会稍微高些。
 
从以上的思路出发，并根据自身产品的特点和实际包装要求，选用合适的的贴体包装膜(贴体膜），就可以降低包装材料成本，同时保证贴体包装效果。
