Transparent plastic protective film characteristics and viscosity selection
- Jun 19, 2018 -

The raw material used for making the transparent plastic protective film is polyurethane film. The raw material itself has the characteristics of scratch resistance, anti-yellowing, and super toughness. Therefore, the transparent plastic protective film is made of a film with superior winding force and retractability. The product is compactly and fixedly bundled into a unit, so that the scattered small pieces become a whole, even if the product is not loose and separated in an adverse environment, and there is no sharp edges and stickiness, so as to avoid damage.


The primary protection of the transparent plastic protective film can provide surface protection of the product, forming a very light protective appearance around the product, so as to achieve the purpose of dust, oil, moisture, water, and theft prevention. It is especially important that the wrapping film wraps the packaging items so that they are evenly subjected to force, so as to avoid damage caused by uneven force. This is not possible with traditional packaging methods.


The use of transparent plastic protective film compression and fixation, the product can be wrapped around to form a compact, space-free unit as a whole, so that the product trays tightly wrapped together, can effectively prevent the mutual transmission of products during the process Misalignment and movement; At the same time, the adjustable stretching force can make the hard products cling to make the soft products shrink, especially in the tobacco industry and the textile industry has a unique packaging effect.


Unlike ordinary protective film, transparent plastic protective film has a strong light transmittance, because they are transparent products, so in the use of the process, pay special attention to the goods or other products that are used in line with the Bonding conditions, only the integrity of the fit, can ensure that they play a protective role.


In order to correctly use the transparent plastic protective film, we must ensure that they are compatible with the product to be protected while paying attention to the viscosity. This is the best way to use, and the best conditions for performance are fulfilled. For the degree of smoothness of different product surfaces, transparent plastic protective films of different tackiness should be selected to meet the requirements for surface attachment.


For example, low-viscosity transparent plastic protective film is suitable for flat, smooth, mirror stainless steel plate, plastic sheet, PMMA, PS board, PC board and other products; medium viscosity products are suitable for stainless steel rough-grained sanding board, snowflake board, aluminum Plastic panels, plastic steel, aluminum and polyester sheet products; and high-viscosity transparent plastic protective film is more suitable for the protection of special products difficult to stick.
