Abstract

The utility model discloses a green paper composite packaging board, which comprises an upper board (1), a lower board (2) and a cardboard (3) between the upper board and the lower board; a bonding adhesive layer (4) is coated with the upper board (1), the lower board (2) and the cardboard (3); a layer of the Kraft paper (5) is covered on the surface of the upper board (1) and the lower board (2); as a layer of the bonding adhesive layer (4) is coated on the inner surface of the upper board (1) and the lower board (2), the intensity of the bond among the upper board (1), the lower board (2) and the cardboard is strong enough and cannot occur degumming cracking phenomenon. In addition, a strong and effective support plate after solidification of the bond adhesive layer (4) and effectively improve the bearing ability of the upper board (1) and the lower board (2). The Kraft paper (5) coated outside plays a role to prevent water and also effectively raise the overall capacity of pressure.

Description

Environmental protection paper composite packaging plate

Technical field the utility model relates to packing, particularly is used for the wrapping paperboard wrapping plate of large piece article.

The general composite packaging plate that adopts folder honeycomb paper core structure between two cardboards of the papery wrapping plate of large piece article adopts paper angle protector to come the reinforced packing plate in the bight in the background technology prior art.This wrapping plate adopts the mode that combines with cardboard at refill termination gluing in manufacturing process, in use, because its bonding dynamics is not strong, often cause the cracking that comes unstuck, so the wrapping plate bearing capacity deficiency of this kind structure causes article to damage; And its complex manufacturing technology, waste material.

Summary of the invention the utility model provides a kind of environmental protection paper composite packaging plate, and its purpose is to solve the deficiency that prior art exists, and improves the bearing capacity of wrapping plate.

The utility model is realized goal of the invention by implementing following technical scheme: make a kind of environmental protection paper composite packaging plate, comprise the refill of upper plate, lower plate and vertical placement between the two; All scribble one deck glue line on the upper plate of described employing card board, the inside face of lower plate and combine with refill respectively, all be covered with one deck craft paper on the outside face of described upper plate and lower plate.Because all full coat has one deck glue line on the inside face of upper plate, lower plate, so the bonding dynamics between upper plate, lower plate and the refill is enough strong, can not produce the cracking phenomena that comes unstuck.In addition, this glue line forms the crash-resistant supporting layer of one deck after curing, improves upper and lower plate bearing capacity effectively, strengthens the intensity of whole wrapping plate.

The utility model is owing to adopt technique scheme, so, having bonding and firmly do not ftracture, bearing capacity improves greatly and manufacture craft is simple and the characteristics of saving in material.

Description of drawings

Fig. 1 is that the master of the utility model environmental protection paper composite packaging plate looks cross-sectional schematic.

Fig. 2 is the expansion scheme drawing of whole paperboard in the utility model.

Fig. 3 is the expansion scheme drawing of whole craft paper 5 in the utility model.

The specific embodiment further describes embodiment of the present utility model below in conjunction with accompanying drawing.

By finding out among Fig. 1, a kind of environmental protection paper composite packaging plate comprises upper plate 1, lower plate 2 and refill between the two 3; It is bonding with refill 3 respectively all to scribble one deck glue line 4 on the upper plate 1 of described employing paperboard core, the inside face of lower plate 2, has all covered one deck craft paper 5 on the outside face of described upper plate 1 and lower plate 2.Because all full coat has one deck glue line 4 on the inside face of upper plate 1, lower plate 2, so the bonding dynamics between upper plate 1, lower plate 2 and the refill 3 is enough strong, can not produce the cracking phenomena that comes unstuck.In addition, this glue line 4 forms the crash-resistant supporting layer of one deck after curing, improves upper plate 1, lower plate 2 bearing capacities effectively, strengthens the intensity of whole wrapping plate.Be coated on outmost craft paper 5 and can play certain waterproof effect, and, can also play the effect that each parts with above-mentioned wrapping plate are integrated into one, can effectively improve the single-piece bearing capacity.

By finding out among Fig. 1, described upper plate 1 and lower plate 2 all around around one deck paperboard 6, this paperboard 6 respectively with upper plate 1 and lower plate 2 bondings, all scribble one deck glue line 4 on described paperboard 6 and the inside face that refill 3 combines, the outside face of this paperboard 6 is covered with one deck craft paper 5.The side of wrapping plate adds paperboard 6, can protect the side of this wrapping plate to withstand shocks and to keep clean on the one hand; Can carry out effective support to upper plate 1 and lower plate 2 on the other hand.

According to the difference of concrete loaded-up condition and user's requirement, described refill 3 is honeycomb paper core or corrugating media, and described corrugating media adopts multi-layered bonded to be integral.Described paperboard 6 can be selected ox card, grey paperboard or fluting board for use.

As can be seen from Figure 1, described paperboard 6 embeds between upper plates 1 and the lower plate 2, its upper and lower two end faces respectively with the inside face bonding of upper plate 1 and lower plate 2.Such structure design can be strengthened the support to upper plate 1 and lower plate 2 more, further improves the single-piece bearing capacity.

Can find out that from Fig. 2 and Fig. 3 described paperboard 6 is to be shaped by whole paperboard cutting with upper plate 1 and lower plate 2, its inside face is coated with glue line 4, and the outside that coats refill 3 forms an entire package plate; Described craft paper 5 is coated on the outside of hard card paper for whole cutting is shaped.The mode that adopts whole cutting to be shaped can make the connectivity between each plate better, and bearing capacity is stronger.

Can find out that from Fig. 2 and Fig. 3 the paperboard that described whole hard cutting is shaped leaves the paper 61 of surplus at cornerite place, the side of this paperboard wrapping plate; Described craft paper 5 leaves the paper 51 of surplus at cornerite place, the side of this paperboard wrapping plate.In manufacturing process, with the bight that

paper

61 and 51 wrapped this wrapping plate, can make the bight not stay the slit, anticorrosion anti-mashed performance is better.

According to the difference of concrete loaded with articles weight and user's requirement, described upper plate 1 or lower plate 2 for double-ply multilayer paperboard at least through being bonded to one; Also can select the paperboard of the different quality of 400～1200G to do upper plate 1 or lower plate 2.
