Abstract

The invention relates to the technical field of packaging films, in particular to a heavy packaging film and a preparation method thereof. The heavy packaging film comprises an aluminum plating layer, a moisture barrier layer and a heavy wrapping layer which are tightly attached in sequence from outside to inside. The prepared film is good in toughness, high in puncture resistance, high in falling resistance and puncture resistance, excellent in mechanical property, and capable of meeting the requirement for heavy packaging. Meanwhile, due to the high moisture-proof and damp-proof performance, the problem that in the prior art, a heavy packaging film is poor in moisture-proof and damp-proof effect is solved. The film layers are formed by mixing the same kind of raw materials, can be recycled and reused and are environmentally friendly. The whole preparation process is safe and reliable and is simple and convenient to operate, and the heavy packaging film has a wide application prospect in the field of packaging films.

Description

technical field [0001] The invention relates to the technical field of packaging films, in particular to a heavy packaging film and a preparation method thereof. Background technique [0002] Film-coated woven bags, paper-plastic composite bags, paper bags and FFS heavy-duty film are the main forms of heavy-duty packaging in the domestic industrial field. With the transition from extensive production mode to intensive production mode, the first three packaging forms have problems such as low packaging efficiency, poor airtightness and water resistance, and unfavorable environmental protection in application, which can no longer meet the requirements of modern packaging. FFS focuses on Carrier film will replace traditional packaging and become the mainstream product of heavy packaging. [0003] FFS heavy-duty film (heavy packaging film) can not only meet the needs of modern packaging of chemical raw materials, but also has broad application prospects for the packaging of agr...
