Description

High-strength PS sheet for blister packaging

Technical Field

The utility model belongs to the technical field of the plastic sheet material and specifically relates to a high strength PS sheet material that blister pack used is related to.

Background

The PS plastic sheet is usually used for blister packaging, and the plastic blister sheet at the present stage is thin, so that the advantages of no resilience and good thermoplastic effect are achieved, but the PS plastic sheet is easy to be pierced by foreign objects or interiors during packaging, the defective rate is increased, and the control of the production cost is not facilitated, so that the high-strength PS sheet for blister packaging needs to be provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high strength PS sheet that blister pack used to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a high strength PS sheet that blister pack used, includes the inner core layer, the equal integrated into one piece shaping of inner core layer front and reverse side be provided with outside bellied spacing attachment point, inner core layer and spacing attachment point surface around being equipped with the glass fiber silk, just glass fiber silk alternately range upon range of winding and establishing, the inner core layer outside in spacing attachment point and glass fiber silk department be formed with the back up coat through the secondary is moulded plastics, the back up coat outside have the plastics coating through thermoplastic bonding.

As a further technical scheme of the utility model, spacing attachment point equidistant set up in the interior sandwich layer openly and on the reverse side.

As a further technical proposal of the utility model, the height of the limit attachment point is 0.15mm to 0.2mm.

As a further technical scheme of the utility model, inner core layer and spacing attachment point be PS plastics integrated into one piece.

As a further technical proposal of the utility model, the thickness of the reinforcing layer is 0.2mm to 0.25mm.

As a further technical proposal of the utility model, the cross lamination angle of the glass fiber yarns is 90 degrees.

As a further technical proposal of the utility model, the thickness of the plastic coating layer is 0.2mm to 0.3mm.

The utility model has the advantages that: through including sandwich layer and spacing attachment point surface around being equipped with the glass fiber silk, realize the effect of one deck parcel, the intensity of reinforcing plastic sheet utilizes the parcel of back up coat and plastics coating simultaneously, can protect the packing material better as the plastic uptake spare, is difficult for being pierced, and intensity is big, and the durability is high, can reuse, saves the cost.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Wherein: the plastic core-spun yarn comprises an inner core layer 1, a reinforcing layer 2, a plastic coating layer 3, a glass fiber yarn 4 and a limiting attachment point 5.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings and preferred embodiments.

Referring to fig. 1, a high-strength PS sheet for blister packaging includes an inner core layer 1, the front and back of the inner core layer 1 are integrally formed with outwardly protruding limit attachment points 5, the outer surfaces of the inner core layer 1 and the limit attachment points 5 are wrapped with glass fiber filaments 4, the glass fiber filaments 4 are alternately stacked and wound, a reinforcing layer 2 is formed at the outer side of the inner core layer 1 at the limit attachment points 5 and the glass fiber filaments 4 by secondary injection molding, a plastic wrapping layer 3 is bonded at the outer side of the reinforcing layer 2 by thermoplastic bonding, the limit attachment points 5 are equidistantly disposed on the front and back of the inner core layer 1, the inner core layer 1 and the limit attachment points 5 are integrally formed of PS plastic, the glass fiber filaments 4 are wrapped at the outer surfaces of the inner core layer 1 and the limit attachment points 5, so that a wrapping effect is achieved, the strength of the plastic sheet is enhanced, and the wrapping layer 2 and the plastic wrapping layer 3 are utilized to wrap the blister package.

Further, the height of the limiting attachment point 5 is 0.15mm to 0.2mm, the thickness of the reinforcing layer 2 is 0.2mm to 0.25mm, the thickness of the plastic cladding layer 3 is 0.2mm to 0.3mm, and the inner core layer 1 is reinforced and wrapped through the reinforcing layer 2 and the plastic cladding layer 3, so that the overall strength is improved.

Furthermore, the cross lamination angle of the glass fiber yarns 4 is 90 degrees, the strength of the glass fiber yarns is enhanced by interweaving and laminating the glass fiber yarns 4, and the glass fiber yarns can better protect a package as a plastic sucking piece and are not easy to puncture.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
