Abstract
The utility model relates to a high-barrier polyvinyl dichloride (PVDC) composite rigid sheet which comprises a PVDC film layer, a binder layer and a rigid sheet layer, wherein the PVDC film layer is bonded with the rigid sheet layer through the binder layer. PVDC is combined with various rigid sheets (such as polyvinyl chloride (PVC), polyethylene terephthalate (PET) and propene polymer (PP)), composites rigidity and thermal forming performance of the rigid sheets and ultrahigh barrier performance of PVDC, the barrier performance is improved by 3-5 times compared with the existing PVDC, water vapor transmission rate can reach 5-6g*mu m/m<2>*24hr, and oxygen transmission rate can reach 10ml*mu m/m<2>*24hr*bar.
Description
Technical field
The utility model relates to a kind of PVDC composite hard sheet, especially relates to a kind of high-barrier PVDC composite hard sheet.
Background technology
PVDC (polyvinylidene chloride); Because its intermolecular cohesive force is strong, degree of crystallinity is high, and the chlorine atom in the PVDC molecule has hydrophobicity; Can not form hydrogen bond; Oxygen molecule and hydrone are difficult in the PVDC molecule and move, thereby it is moist with resistance to make it have good resistance oxygen property, and its resistance oxygen property does not receive the influence of ambient humidity.That is to say, under any temperature or damp condition, have the ability of remarkable obstruct steam, oxygen, smell and fragrance concurrently, is the best plastic package material of combination property aspect barrier of generally acknowledging at present.
PVDC Chang Zuowei composite or monomer material and coextruded film sheet are to use maximum high barrier packaging material, and wherein PVDC coated film use amount is many especially.
General PVDC steam transmitance is 15-30 g μ m/m
224hr, OTR oxygen transmission rate are 40-60 ml μ m/m
224hrbar.
The utility model content
For reaching the raising barrier property, reduce the use amount of packaging material, prolong the purpose of food, expiration date of drug, the utility model provides a kind of high-barrier PVDC composite hard sheet.
A kind of high-barrier PVDC composite hard sheet, described composite hard sheet comprise PVDC rete, adhesive phase and hard sheet layer, and described PVDC rete and hard sheet layer are bonding through adhesive phase.
The utility model makes PVDC combine with various rigid plastics sheets (comprising PVC, PET, PP etc.); The rigidity of hard sheet and the superelevation barrier of hot formability and PVDC have been made up; Compare barrier property with original PVDC and improved 3-5 doubly, the steam transmitance can reach 5-6 g μ m/m
224hr, OTR oxygen transmission rate can reach 10ml μ m/m
224hrbar.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, but the protection domain of the utility model is not limited in this.
With reference to Fig. 1, a kind of high-barrier PVDC composite hard sheet, described composite hard sheet comprise PVDC rete 1, adhesive phase 2 and hard sheet layer 3, and described PVDC rete 1 is bonding through adhesive phase 2 with hard sheet layer 3.
Described adhesive is polyurethane binder, and described hard sheet is PVC.
Make PVDC and PVC bonding through polyurethane binder, the steam transmitance of this composite hard sheet is 5g μ m/m
224hr, OTR oxygen transmission rate are 10ml μ m/m
224hrbar.
Embodiment 2
With reference to Fig. 1, a kind of high-barrier PVDC composite hard sheet, described composite hard sheet comprise PVDC rete 1, adhesive phase 2 and hard sheet layer 3, and described PVDC rete 1 is bonding through adhesive phase 2 with hard sheet layer 3.
Described adhesive is polyurethane binder, and described hard sheet is PP.
Make PVDC and PP bonding through polyurethane binder, the steam transmitance of this composite hard sheet is 6g μ m/m
224hr, OTR oxygen transmission rate are 12ml μ m/m
224hrbar.
