packaging paper box Nowadays, cardboard boxes have become popular in the market, and people are interested in various types of products carton packaging The design requirements are very high. Therefore, there are several different design methods for packaging paper boxes or carton production in the market.

There are four main design methods for cardboard boxes or cardboard box production:
① Single sided corrugated cardboard (single sheet), offset printing color printing paper (single sheet) → laminating and bonding synthetic cardboard → die-cutting and slotting → bonding nail box
② Corrugated cardboard production → direct printing of cardboard (flexible version) → die-cutting and slotting → adhesive nail box
③ Micro corrugated cardboard production → Micro cardboard direct offset printing → Die cutting and slotting → Adhesive nail box
④ Pre printed surface paper on roll paper (gravure printing, flexographic printing), corrugated composite bonding produced on production lines → computerized longitudinal cutting → computerized transverse cutting → die-cutting and slotting → adhesive nail box. Looking at the various ways of making cardboard boxes mentioned above, their characteristics and advantages are as follows.
Strategy and Functional Analysis of Paper Box Packaging Structure Design
The first method is to use adhesive printing on corrugated cardboard box surface paper, and then use a single machine to laminate the corrugated paper. This method can print beautifully patterned cardboard boxes, improving the printing quality of cardboard products, but it also brings about other problems: complex production processes and long production cycles; Low strength of cardboard boxes, high scrap rate, and high production costs; Large production site and high labor intensity; Limited printing format; The delivery time is not flexible enough, etc.
The second method is direct printing of corrugated cardboard using flexographic printing, which has the characteristics of fast ink drying, high-speed printing, and low cost, and is particularly suitable for printing on corrugated paper, which does not require high printing accuracy.
The third method is to obtain exquisite patterns through adhesive printing on micro corrugated cardboard, which is a new material and printing overlay technology. The packaging products produced using micro corrugated materials have the characteristics of low weight and high strength, while the high-end color corrugated cardboard printed directly by offset printing has the characteristics of short production cycle and good dimensional stability.
The fourth method can produce medium to high-end cardboard boxes. The requirements for medium to high-end cardboard boxes for corrugated paper are: exquisite printing patterns, and the strength of corrugated paper cannot be affected. The ideal way to meet such requirements is currently pre printing, which includes two printing methods: gravure pre printing and flexographic pre printing.
