The complete manufacturing process for corrugated boxes (an overview of the entire system).
The complete production process system of corrugated boxes is divided into five categories: cardboard substrate process, forming process, printing decoration process, splice forming process and special deep processing process, which is the complete production process of the industry:
I. Wallboard substrate process (preliminary basic process)
This is the underlying process of the quality of all corrugated boxes, which determines the hardness, cushioning, and bearing weight.
Layer number composite process
Single layer corrugated: paper + corrugated core, thin and low weight
Three layers of corrugated: face paper + corrugated core + inside paper, mainstream of general purpose civil packaging
Five layers / Seven layers of corrugated: multi-layer composite with high strength, heavy load, and shock resistance for industrial large-piece packaging
Cranial molding process
By pressing different waves through the corrugated roller, the buffer and printing effect are determined:
A leng: high buffer, suitable for fragile products
B Corrugated: flat and compression-resistant, suitable for express boxes
C leng: comprehensive balance, the most versatile

E / F / G micro leng: smooth and delicate surface, suitable for fine color box, HD printing

II. Box forming process (the core process of cardboard turning into boxes)
The groove cutting process
Standard delivery boxes and ordinary cartons are mainstream, high-speed mass production, low cost, and suitable for regular rectangular boxes.
Moulding molding process
Custom boxes, exotic boxes, and boutique boxes are necessary, which are divided into flat pressing, round pressing, and round molding, and can be made for airplane boxes, suitcases, open window boxes, shape structures, and button structures.
Pre-printed integrated molding process
High-end mass production process: preprint original paper before composite corrugated, with stable color, non-deformation, and no scratches.
Semi-manual molding process

Sampling, ultra-large sizes, specialty processes for special exotic boxes.

III. Print and surface decoration processes (pigment processes)
Flexible Ink Printing: Environmentally Friendly, Low Cost, Bulk Universal Box
Pigment coating processes: high-definition color, gradient patterns, mainstream boutique gift boxes
Digital direct spraying process: no print fee, small volume customization, personalized printing
Film coating process: bright film / muted film, waterproof and wear resistant, improved texture

Special process: bronzing, UV, hit convex, concave, hollow, flocking (high-end gift box)

IV. Splicing patterning process (box fixing process)
Sealing process: flat and beautiful, seamless, suitable for e-commerce boxes and boutique boxes
The nail box process: high strength and strong bearing weight for heavy industrial cartons

Plastic-free button-free process: environmentally friendly, removable, without additives, food-grade safety

V. Functional deep processing processes (special scenario processes)
Water resistance: gonorrhea film, waterproof oil, waterproof film
Shock proof buffer: built-in cellular structure, buffer lining moulded
Antistatic treatment: specialty for electronic packaging

Airtight preservation perforations: specialty for fresh fruit and vegetable boxes

In a word, we summarize the whole process:
Raw paper composite sheeting → closure molding → printing decoration → molding / groove molding → glue / nail / button molding → functional deep processing.
