Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The degradable composite membrane as shown in fig. 1 comprises a PLA substrate layer 1, and is characterized in that: PVC degradation layers 2 are distributed on the upper side and the lower side of the PLA substrate layer 1. Therefore, the PLA substrate layer 1 has high hardness, and can meet various use and shaping requirements of wrapping, plastic packaging and the like of the membrane. Through the cooperation of PVC degradation layer 2, can realize the effective self degradation after abandonment. Meanwhile, a main color layer 3 is distributed on the PVC degradation layer 2 at the upper end, and an auxiliary color layer 5 is distributed on the PVC degradation layer 2 at the lower end. Like this, can let final diaphragm possess positive and negative different colours according to actual need, or the homochromy, or possess different patterns, satisfy different decoration needs, be convenient for the diaphragm finished product to use on the different packing. And, the utility model discloses it has PP highlight stratum lucidum 4 to distribute on main colour layer 3. In this way, the presentation of the main colour layer 3 is not affected and it can be suitably protected. Similarly, a PP highlight wear layer 6 may be distributed on the secondary color layer 5. From this, satisfy under the prerequisite of vice colour layer 5 protection show, can provide suitable wear-resisting effect, improve life, can not be because of outside scraping and rubbing and cracked. Therefore, various conventional packaging auxiliary requirements such as packaging, plastic packaging and the like can be met.

In combination with the preferred embodiment of the present invention, the thickness of the PLA substrate layer 1 is 0.5 to 1.5 mm, and the thickness of the PVC degradation layer 2 is 0.1 to 0.5 mm. Like this, can satisfy daily use needs, possess suitable bearing effect, also possess certain deformation characteristic, when realizing the packing buffering, can satisfy moulding needs. Through many times contrast test discovery, the thickness of PLA substrate layer 1 is 1 millimeter, and the thickness of PVC degradation layer 2 is 0.2 millimeter, can realize the self degradation of rapidization after abandonment when satisfying daily user demand.

Further, the primary color layer 3 and the secondary color layer 5 are ink spraying layers, ink printing layers, transfer printing layers or pasting paper layers. Like this, satisfy different decoration, sign needs, let utility model can demonstrate the same pattern of positive and negative or different patterns, satisfy different user demands.

In connection with practical implementation, the thickness of the PP highlight transparent layer 4 is 0.3 to 1 mm. Thus, the main color layer 3 is not shielded, and the main color layer 3 is prevented from being worn. Meanwhile, the thickness of the PP highlight wear-resistant layer 6 is 0.4-1.5 mm. Thus, the sub color layer 5 is not blocked during the protection period, and has better display definition. In addition, the anti-skid and wear-resistant functions can be realized, and the contents can be better protected when the anti-skid and wear-resistant protective bag is used as a packing material or an inner support. Through many times of contrast tests, the thickness of the PP highlight transparent layer 4 is 0.5 mm, and the thickness of the PP highlight wear-resistant layer 6 is 0.8 mm, so that the daily processing and use requirements can be met. Of course, for some special use requirements, the corresponding processing may also be performed by using values outside the range, which is not described herein again.

In addition, considering that better anti-skid and wear-resistant effects are achieved during daily use, a plurality of wear-resistant protrusions are distributed on the outer surface of the PP highlight wear-resistant layer 6. Or a plurality of wear-resistant convex strips are distributed on the outer surface of the PP highlight wear-resistant layer 6. Like this, rely on wear-resisting arch, wear-resisting sand grip, can avoid sharp object directly to rub the surface of PP highlight wearing layer 6 during scraping, do not influence the show on vice colour layer 5.

Seen in combination with practical use, can be right the utility model discloses tailor, different processing methods such as plastic uptake realize the parcel to content. After the belt is discarded, the belt can be cut for the second time and is placed in a designated place to be accumulated for self-degradation. Meanwhile, even if the PVC film is improperly discarded, the PLA substrate layer 1 and the PVC degradation layer 2 can be matched with each other to synchronously degrade other layers.
