What are the advantages and disadvantages of PVC body membrane?
In the past 20 years, China has rapidly emerged as an export-oriented economy, and small commodities packed with PVC-fitted packaging films (attachment membranes) have been continuously delivered to every corner of the world. This is also a powerful Chinese manufacturing economy. Powerful testimony. As a small commodity manufacturer, it is necessary to understand the advantages and disadvantages of the PVC body packaging film (fitted body membrane). Because fully understand the characteristics of this packaging film material, give full play to its advantages, to avoid its shortcomings, to achieve the best body packaging effect.
The chemical name of PVC is polyvinyl chloride, and the film products made of it are divided into hard film and soft film. The main body of the packaging film is rigid PVC sheet.
The rigid PVC film has a very high transparency. This feature is a great advantage for body-fitting packaging, because the body-fitting packaging is essentially a visual display package for shopping mall shelves. The transparency of the packaging film is very high. High-gloss, high-transparent packaging film allows better visual effects of the body-fitted packaging products.
Another advantage of PVC skin film is its low cost. Of all body-fit membranes, it is the lowest-priced variety. For the most demanding low-cost packaging needs, consider it.
Due to its inherent physical properties, PVC skin packaging films have poor tensile properties. Skin-fitting packaging is to heat and soften the film under the action of vacuum plastic film, the film will be tightly shaped according to the product shape, and paste on the cardboard above the product. The main standard thickness of PVC body coating is 0.06, 0.08, 0.10, 0.12, 0.15, 0.20MM. The tensile properties of PVC are somewhat poorer. Therefore, the products with low packaging heights and relatively standardized shapes are still relatively satisfactory. For example, small products such as hardware products, hardware tools, and car accessories that are packed within 2 CM height can be used in thicknesses of 0.06-0.08 MM. However, if the product is relatively high and the shape is irregular, the PVC skin packaging film can easily be broken under strong vacuum suction, resulting in that the PVC film around the product cannot be properly sucked into position (in a popular sense, the membrane is stretched) . This leads to poor packaging results.
Another disadvantage of the PVC body patch is that it is relatively brittle at low temperatures (below 5 degrees). The possible consequence of this defect is that the packaging film is embrittled, the packaged product is scattered, and the body bundle is lost to the effect of protecting the packaging. Therefore, it is recommended that the product not be used in low temperature areas or countries. This is not the case unless the price of the packaging film is the first consideration.
Another disadvantage of PVC film is that it is not environmentally friendly. Can not be used to directly package food. Some countries will ban the use of PVC material packaging. In this case, customers in some areas do not have clear requirements for environmental protection and can use this membrane.
