s9, printing: adopting offset printing or letterpress printing, wherein the carton surface paper is printed in the offset printing, then the printed surface paper is pasted on the corrugated paper, for the letterpress printing, the corrugated paper is longitudinally input into a rotary printing machine, a rubber letterpress is arranged on a round plate cylinder, a group of rollers are arranged on the upper part of a plate roller, the well-adjusted ink is uniformly transferred to letterpress pattern characters, and then the letterpress pattern characters are transferred to a paper board by the plate roller;
s10, bonding: connecting corrugated paper edges by adopting nailing, bonding or adhesive tape sticking so as to manufacture a corrugated paper box;
s11, spraying: spraying a layer of moistureproof oil on the surface of the corrugated case;
and S12, drying, cutting and storing.
From comparative example 2, it can be seen that: the carton yield through above-mentioned scheme machine-shaping is lower, and dampproofing effect is relatively poor, and anti deformation effect is relatively poor, and life is short, can't satisfy the requirement of leaving the factory.
The carton end products obtained in the examples and the comparative examples are detected to obtain the following table:
detecting items Example 1 Example 2 Example 3 Comparative example 1 Comparative example 2
Yield of finished products Height of Height of Height of Is low in Is low in
Moisture resistance Is excellent in Is excellent in Is excellent in Is poor Is poor
Resistance to deformation Is excellent in Is excellent in Is excellent in Is poor Is poor
Service life Long and long Long and long Long and long Short length Short length
The table shows that the finished product rate of the carton obtained in the embodiment is high, the moisture-proof effect is excellent, the deformation resistance effect is excellent, the service life is long, and the factory leaving requirement can be met, and the finished product rate of the carton obtained in the comparative example is low, the moisture-proof effect is poor, the deformation resistance effect is poor, the service life is short, and the factory leaving requirement cannot be met.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
