Problems solved by technology

[0003] However, the current BOPP heat-sealing film for packaging bags has the following problems when slitting. 1. When cutting the existing BOPP heat-sealing film for packaging bags, the distance between the knives needs to be adjusted, but the traditional slitting mechanism is integrated. The knives need to be replaced with different spacing knives, which is more troublesome and reduces the cutting efficiency and quality of the BOPP heat-sealing film of the packaging bag; 2. After the BOPP heat-sealing film of the packaging bag is cut, it cannot be wound stably , affecting the winding efficiency and quality of BOPP heat-sealing film for packaging bags

Embodiment Construction

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0035] see figure 1 , a preparation process of BOPP heat-sealing film for packaging bags, mainly comprising the following steps:

[0036] Step 1, raw material treatment, carry out low temperature vacuum pretreatment on the raw material of the BOPP heat-sealing film of the packaging bag to obtain modified raw materials;

[0037] In step 2, extrusion operation, the modified raw material obtained in step 1 is transported into an existing extruder to obtain an extruded BOPP base film;

[0038] Step 3, cooling the corona, cooling the extruded BOPP base film obtained in the second step, and subjecting the cooled BOPP base film to corona treatment to obtain a finished BOPP base film;

[0039] Step 4: Rewinding and slitting, using the existing BOPP heat-se...

Abstract

The invention relates to a preparation process of a BOPP heat-sealing film for packaging bags, which mainly includes the following steps: raw material processing, extrusion operation, cooling corona, winding and slitting and other processes, and the used BOPP heat-sealing film slitting equipment. It includes an operating table, a roll feeding mechanism, a cutting mechanism and a rewinding mechanism. The left end of the operating table is provided with a roll feeding mechanism, a cutting mechanism is installed in the middle of the operating table, and a winding mechanism is installed on the right end of the operating table. The following problems exist in the slitting of BOPP heat-sealing film for packaging bags. First, the existing BOPP heat-sealing film for packaging bags needs to adjust the distance between the knives when slitting, but the traditional slitting mechanism is an integrated knife. It is more troublesome to replace the knives with different spacings, which reduces the slitting efficiency and quality of the BOPP heat-sealing film for packaging bags; 2. After the BOPP heat-sealing film for packaging bags is slit, it cannot be stably wound. It affects the winding efficiency and quality of BOPP heat-sealing film for packaging bags.

Description

technical field [0001] The invention relates to the technical field of BOPP heat-sealing film production, in particular to a preparation process of a BOPP heat-sealing film for packaging bags. Background technique [0002] BOPP heat sealing film for packaging bags, mainly used for compound bag making or wrapping packaging. It is divided into single-sided heat-sealing film and double-sided heat-sealing film. After printing the pattern on the non-heat-sealing layer, the BOPP heat-sealing film of the packaging bag is compounded with PE, BOPP and aluminum foil to make bags for the packaging of food, tea, beverages, etc. After the BOPP heat-sealing film of the packaging bag is rolled and formed, it needs to be Cut the BOPP heat-sealing film of equal width to facilitate the subsequent use of the BOPP heat-sealing film for packaging bags. [0003] However, the current BOPP heat-sealing film for packaging bags has the following problems when slitting: 1. When the existing BOPP hea...
