Large-capacity asphalt flexible packaging bags will replace barrel packaging

A large-capacity flexible packaging bag capable of filling 100 to 500 kilograms of asphalt was successfully developed at Dalian Xinke Packaging Materials Co., Ltd. and put into mass production.

Last year, Dalian Xinke once successfully developed asphalt soft packaging bags with a paper composite capacity of less than 50 kilograms, which changed the history of China’s long-term use of iron drums for asphalt packaging. However, the company found through investigation of users that the necessary filling equipment for the paper-based composite asphalt soft packs required investment of more than 2 million yuan for each filling line, including the plant, thus limiting the promotion and application of asphalt packaging bags. To this end, from the beginning of this year, Dalian Xinke's engineering and technical personnel set out to develop a new type of asphalt soft packaging bags.

This large-capacity bituminous flexible packaging bag is made of chemically treated cloth and has a heat-resisting temperature of 300°C or more. Both natural cooling and water cooling can be used, and mechanical lifting can be used after filling to save man-hours and reduce labor intensity. . At the same time, this new type of bag has different capacity specifications from 100 to 500 kilograms, and can directly use the original filling equipment, which saves a huge investment in the purchase of filling equipment.

In addition, this kind of large-capacity asphalt soft-packaging bag also has the advantages of protection against rain and snow, easy stacking and transportation, and easy peeling. It has now applied for national patents.
