AI Technical Summary
Technical Problem
Existing express folding boxes are prone to scratches during transportation, and the adhesive of the express information sheet is difficult to clean.
Method used
The surface matte folding box processing technology is used to form surface matte plates through extrusion and hot pressing composite technology to reduce the contact between the adhesive and the box.
Benefits of technology
It improves the strength and flatness of the folding box, hides small scratches, reduces the adhesive sticks to the box, and makes it easier to tear off the express order.

Abstract
The invention discloses a processing technology for a folding box with a frosted surface. The processing technology comprises the following operation steps that S1, a lower layer film, a core layer and a frosted upper layer film which are independent of one another are formed through extrusion molding; s2, performing first hot-pressing compounding on the upper-layer film and the core layer; s3, the upper layer film, the core layer and the lower layer film are subjected to first-time hot-pressing compounding and are heated in two times to be in a molten state and then pressed, and the formed plate is high in strength; S4, the plate is subjected to first-time natural cooling; S5, the plate is subjected to second-time heating, internal stress is eliminated, the heat shrinkage rate is reduced after the plate is cooled again, and the flatness of the plate is improved; s7, cutting for the first time to form a rectangular plate for manufacturing the folding box, and S8, cutting for the second time, namely cutting off the redundant plate, carrying out hot melting and edge sealing, and carrying out hot pressing to form folding marks at the same time; and S9, the plate is folded into the folding box along the folding marks.
