Shijiazhuang Refinery made a new breakthrough in the thinning of double-film polypropylene packaging

On May 17th, Shijiazhuang Refinery and Chemical Co.
, Ltd.
successfully tackled key problems in the first batch of polypropylene 0.
12 mm heavy film packaging and 0.
10 mm cold stretch film sleeves.
The stretch film sleeve has reached the advanced level in the same industry, which not only promotes the upgrading of the synthetic resin packaging materials of the enterprise, but also creates more than 2 million yuan for the enterprise
.

Shilian polypropylene heavy film packaging line adopts 0.
18mm thick film roll
.
In 2020, the film reduction was successful twice, and the packaging heavy film was "slim down" to 0.
16 mm and 0.
14 mm successively
.

This year, the company has kept a close eye on the market demand, conducted repeated investigations, and comprehensively tracked feedback in all aspects of packaging, palletizing, in and out of storage, loading, and customer use.
The film formulation and 0.
10mm cold stretch film sleeves have been improved to promote the upgrading of synthetic resin packaging materials
.

Shilian carefully organized and strictly followed the requirements of Sinopec's standards, and formulated a trial plan for heavy-film packaging and sleeve film in advance
.
Responses and safety measures are formulated for problems that may arise during the debugging process
.
On the premise of meeting the production requirements of the device and ensuring the normal operation of the packaging line, debugging work such as sealing temperature, film drawing speed and film preheating temperature has been carried out many times
.

At the beginning of May, the technicians of the polypropylene plant carried out drop resistance and tensile tests on the 25kg polypropylene 0.
12mm heavy film packaging and the 0.
10mm cold stretch film sleeve according to the industry requirements.
Both films met the industry standard requirements.
The film reduction was successful, and the thickness of the thinned packaging film reached the advanced level in the domestic industry.
At the same time, under the premise of meeting the needs of use, the amount of packaging materials was reduced, and the packaging cost was greatly reduced.
Efforts have been made for enterprises to reduce costs and increase efficiency and promote green environmental protection work
