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 composite sheet suitable for the compression molding process of tableware according to fig. 1 to 2 comprises a PVC substrate layer 1, which is distinguished in that: the inboard of PVC substrate layer 1 is provided with PBAT tectorial membrane layer 2, can avoid the grease infiltration during the material is eaten to the holding like this, ensures the integrality of tableware during the use. Meanwhile, the outer side of the PVC base material layer 1 is provided with a labeling layer 3. Therefore, the tableware can be subjected to appropriate numerical value marking or decorative pattern distribution depending on the existence of the marking layer 3, so that the tableware formed subsequently is more attractive. The utility model discloses it has PP stratum lucidum 4 to coat at the mark layer 3. Like this, can possess certain wear-resisting effect, also can keep apart outside foreign matter when protecting mark layer 3, can not invade PVC substrate layer 1, improve the sanitary effect of use of tableware. Seen in combination with the actual manufacturing, the thickness of the PVC base material layer 1 who adopts is 1 to 3 millimeters, possess the anti deformation support ability of preferred, can not appear distorting because of placing of eating the material after the tableware takes shape, ensure to eat the effective of material and hold. The PBAT coating layer 2 used has a thickness of 0.2 to 1 mm. Therefore, the oil stain remover can deal with normal scraping and oil stain overflow caused by damage can be avoided. Furthermore, the utility model discloses still laminate PP antifouling film 5 on PBAT tectorial membrane layer 2. Therefore, after the PVC substrate is subjected to aseptic painting treatment, the surface of the PVC substrate can be isolated, and pollution can not be caused during compression molding. When the food materials are contained, the PP antifouling film 5 is torn off, so that the food safety is ensured.

In view of the preferred embodiment of the present invention, the label layer 3 is a paper layer, or the label layer 3 is a pigment coating layer. Therefore, for the decoration with more complex patterns, the rapid layout which is convenient and fast can be realized by adopting the paper pasting layer. If some simple single-color marks and decorations are adopted, edible pigment layout can be adopted, so that the distribution of single-color pattern blocks of a large base is met, and the use safety of the tableware is ensured. During the implementation, the appearance of the tableware can have different colors or figures, and the effective marking and decorating effect is met. Meanwhile, in order to realize effective product tracing, a marking area can be further arranged on the PP transparent layer 4, and a steel seal is arranged on the marking area. Therefore, the type of the current composite sheet can be rapidly identified, and the material can be conveniently selected according to the processing requirements of different tableware.

Further see, for tableware after final shaping possess better anti deformation effect, be provided with a plurality of additional strengthening on the PVC substrate layer 1, the additional strengthening is the netted diaphragm 6 of PP. Like this, can realize PVC substrate layer 1's surperficial auxiliary stay, even if receive both hands pressfitting, hold between fingers, also be difficult for appearing the distortion. Meanwhile, in order to realize the transmission of stress and avoid the fracture of the PP reticular membrane 6 caused by excessive concentration at a certain point, the PP reticular membrane 6 is distributed in a # -shaped manner or in a honeycomb-shaped manner.

In connection with practical implementation, the thickness of the PVC substrate layer 1 is 1.5 mm, taking into account the effective load bearing. Meanwhile, the thickness of the PBAT coating layer 2 was 0.6 mm. The PP transparent layer 4 has a thickness of 1 mm. Of course, the thickness of the PVC substrate layer 1 can exceed 3 mm according to certain special use requirements, and the implementation requirements of some large-volume tableware are met. And the thickness of other layers can exceed the preset range, so that more flexible manufacturing adjustment is realized.

Through foretell expression of characters and combination of the attached drawing can be seen, adopt the utility model discloses afterwards, possess following advantage:

3. Through the mutual cooperation of the marking layer and the PP transparent layer, the appropriate decoration requirement is met, and different appearance performances are possessed.
