The superior performance and development direction of stretch film

The superior performance and development direction of stretch film

In the industry according to the grade of agrofilm will have the function of mist - eliminating 

stretch film into three grades.

1. Mist free stretch film, the stretch film has no fog for most of the trial period. When the fog is generated, only the top of the shed 

is surrounded by fog, which can disappear within 0.5-1h. This kind of stretch film has good transparency, good dripping, and can clearly see the scene in the shed in 

the distance. In order to achieve this condition, it is necessary not only to add the spray but also to use the better flow drops, heat preservation agents, resin and 

other mutual coordination to achieve, so this kind of stretch film price is high.

2. Anti-fog stretch film, the stretch film is basically free of fog during the trial 

period. When the fog is generated, it is sometimes surrounded on the roof and sometimes diffuses into the whole shed. Fog will disappear within 1-2 hours, with more 

light fog. Fog can be eliminated, but it will take some time. This kind of stretch film has good transparency. Jining hongxiang packing material co., LTD. 's stretch 

film can achieve this effect. Compared with polyolefin shrink film, the price is about 40% lower.

Fog 3 minus stretch film, the stretch film in use early effects of 

reducing fog, this effect lasts about six months, stretch film surface with sticky substance, dripping condition is bad, on behalf of the product is ordinary 

polyethylene is three stretch film.

Stretch film is a key material to improve the efficiency of packing and produce fruits and vegetables against season. Over the 

years, the problem of short aging time of flow droplet defogging function of stretch film has not been solved effectively. At present, the production of polyolefin 

flow droplet defogging stretch film is mainly produced by means of internal addition, but the spray defogging period is relatively short, generally within three to 

four months. The second production method is grouting stretch film, but the stretch film produced in this way is covered with a lot of water, which has the 

disadvantages of poor adhesion ability and difficulty in transportation and ceiling. In the past two years, the corona - soaking - drying process stretch film, corona 

drying USES a lot of power, and is curly, difficult to transport, and has not formed a batch production. Therefore, the production of stretch film by online spraying 

is the common goal of the same industry at home and abroad. However, all previous experiments were conducted by spraying a single liquid inside the membrane bubble. 

The spray liquid composed of several components was easy to form agglomeration and failed to achieve success due to poor adhesion ability. Jining hongxiang packing 

material co., LTD production of stretch film using # # into the high-tech and high quality at home and abroad of polymer composite materials processing technology, 

with other types of polyolefin shrink film, pof shrink film) the incomparable superiority. Fundamentally solves the troubled stretch film years of dripping fog 

dissipation function and service life can't sync problem, is popular among the broad masses of farmers, is the pallet stretch film updated products, in the stretch 

film development has epoch-making significance. It is a high-end product in the whole type of stretch film. It is the development direction of stretch film in the next 

few years.
