Which is better, hot peel or cold peel

Heat transfer is widely used in T-shirt printing. When choosing to customize, we should focus on the color of the pattern and the method of heat transfer, and decide the way to tear off the film. Now there are mostly two ways in the market: hot peeling and cold peeling. Next, we will analyze these two ways from the following aspects: composition of the ingredient, pressing temperature, pressing time, film tearing time, glossiness and so on.

First of all, composition of the ingredient.

  1. Hot peel. In order to achieve the effect of quick tearing, the main component of the release layer is wax, which is very unstable, not easy to melt and apply. For example, when we apply a release layer on the pet film, if a large amount of wax is applied, it is difficult to ensure uniformity.
  2. Cold peel. The release layer is dominated by the chemical component silicon, and the stability is much better than that of wax, which is easier to apply to the film, and the cold tear film is relatively stable. The cold tear film market is very mature, and Korean hot stamping is the principle of cold tear film.

Secondly, Pressing temperature.

  1. Hot peel . The required pressing temperature is generally between 140-150 ° C.
  2. Cold peel. The required pressing temperature is higher than that of the hot tear film, generally at 150-170 ° C, which needs to be determined according to the specific situation.

Thirdly, Pressing time.

  1. Hot peel: the pressing time is about 5-7 seconds.
  2. Cold peel: The pressing time needs to be determined according to the specific fabric.

Next, tear film time.

  1. Hot peel:  2-3 seconds can be satisfied to tear.
  2. Cold peel: It maybe about 30 seconds can tear film.

Then, glossiness.

  1. Hot peel. After the transfer, the color will be more vivid, there are the following two reasons for reference:

(1) Due to the coating, the hot tear film has a strong ability to absorb ink, so the color after transfering is more vivid.

(2) After the hot tear film is cooled, it may cause color to adhere to the membrane, so that the effect is not well.

2.Cold peel. In general, the color of cold tear film is not as vivid as hot tear film.

Meawhile, wash firmness.

  1. Hot peel. The specifications of the hot tear engraving film on the market are generally 60cm wide, and after the hot heat is torn off, its adhesive layer adopts a water-based back coating process, if it is not torn off in time, the cooled glue will stick to the clothing, causing the tearing difficulty between the clothes and the film. Moreover, the water-based glue layer, for long-term water washing, fastness can not be guaranteed.
  2. Cold peel. The specification of cold tearing is generally 50cm wide, and then it is torn off after being cooled, and its adhesive layer adopts oil-based back-coating process, and the fastness is better.
