To make crystal stickers, one equipment with strong performance is necessary, but do you know? Supporting consumables also need to be carefully selected. 
After all, in addition to glue, there is another important factor that determines the firmness of crystal sticker transfer - the basic film. 
Today I will explain to you a question that many customers are concerned about: White basic film or transparent basic film? Which one is better?

The structure of the finished AB film is similar to the sandwich principle and consists of three layers, namely a thin protective film on the surface, a crystal film in the middle and a basic film. The basic film is a key factor in determining whether the crystal sticker can be transferred completely and easily.

A high-quality backing paper must first have appropriate viscosity and hardness. It must firmly adhere to the pattern and at the same time be easy to separate. Even complex and tiny patterns can be easily transferred to the transfer paper. 

Secondly, it must have stable chemical properties. When the temperature and humidity of the surrounding environment change, its length and width can be kept unchanged to avoid wrinkles and deformation of the base paper, which will affect the pattern and final printing effect.

There are generally two types of crystal sticker background papers on the market: transparent basic film & white basic film. Next, I will explain the differences, advantages and disadvantages between the two in detail.

Transparent basic film
It is a transparent release basic film. At the same meter, it is smaller in size and lighter in weight, making it easier to transport. During the printing process, it is easier to monitor the printing effect and make adjustments at any time.
However, it also has a disadvantage, it has higher requirements on the printer's paper feeding system and is prone to wrinkles.
White basic film
White basic film, which is more environmentally friendly. Because of its white basic, the finished product display effect is better.
There are also disadvantages. For instance, under the same meter, the volume is larger and naturally heavier; during the printing process, the monitoring film effect is poor. Also note that due to its material characteristics and good water absorption, it is more susceptible to moisture and needs to be properly stored in a cool and dry environment.

In order to pursue profits, many manufacturers use cheap materials for the basic film and transfer film. Everyone needs to master the following knowledge points:
1. Glue plays a decisive role
Glue determines whether the finished product will be cracked, drawn, glue overflowed, etc. Before printing the finished product, it is impossible to tell whether the glue is good or bad. Apart from buying it back for testing, the only option is not to be cheap and try to choose mature products that have been tested by the market. For products, it is best to first look at the supplier’s finished products, try them out, and then purchase them in bulk step by step.
2. Background paper
The key to determining the difficulty of crystal mark transfer is not only the glue but also the basic film.
3. Transfer film
The transfer film is also B film, which is the transparent waste film that is covered on the A film to transfer the pattern of the printing layer. Since it is a waste material, many people use the sealing film on the thermal laminating machine, which is also the reason for unstable quality. .
The thickness and high temperature resistance of the film are very important, as they determine whether the finished product will curl when placed, or whether the film will not fall off (not completely separate from the pattern) after transfer.

The basic film is an important part of determining whether the crystal sticker can be transferred completely and easily. The high-quality basic film can firmly adhere the pattern, but it is easy to pick up and separate when transferring. Even small strokes of text can be easily separated onto the transfer paper. And the chemical properties are stable, ensuring that when the temperature and humidity of the surrounding environment change, the length and width of the basic film remain unchanged, so as to avoid wrinkles and deformation of the basic film, which will affect the pattern. The layers of crystal sticker basic films on the market are uneven. How to choose a high-quality, low-cost, strong adhesion backing paper is the key to printing perfect crystal stickers.

How to choose the right crystal sticker basic film?
1. The basic film is made of high-quality Singer release film
2. The texture is dense and uniform, with good internal strength and light transmittance.
3. High temperature resistance, moisture-proof, oil-proof and other functions
4. It can firmly stick to the pattern, has strong adhesion, and is easy to pick up and separate when re-posting.
Only by understanding the precautions can you avoid quality problems caused by consumables.
Finally, remind everyone: Choose materials reasonably and avoid trial and error costs to the greatest extent!
