Utility model content
In view of this, main purpose of the present utility model is to provide a kind of high-low temperature resistant high-barrier food packaging safety sealed membrane, pass through the technical program, by different performance polyblend, be combined in one by different characteristic optimizings, with polyolefin HDPE layer for continuous phase, the polymer evoh layer of high barrier is decentralized photo, obtain the blending and modifying polymeric layer HDPE-EVOH of function admirable, recycle dry compounding machine and obtain HDPE-EVOH/PE composite membrane.
In order to achieve the above object, the technical solution of the utility model is achieved in that. a kind of high-low temperature resistant high-barrier food packaging safety sealed membrane, comprise PE layer, also comprise blending and modifying polymeric layer, described blending and modifying polymeric layer is made up of HDPE layer and evoh layer, by blending technology, HDPE layer and evoh layer are polymerized to one, described blending and modifying polymeric layer utilizes dry compound machine to be compounded on PE layer.
As further technical scheme, the evoh layer in described blending and modifying polymeric layer utilizes dry compound machine to be compounded on PE layer.
Described HDPE layer thickness is 0.02-0.05mm, and described evoh layer thickness is 0.01-0.02mm, and described PE layer thickness is 0.10-0.15mm.
Beneficial effect after employing technique scheme is: a kind of high-low temperature resistant high-barrier food packaging safety sealed membrane, by the technical program, directly adopts blending technology by HDPE layer and evoh layer, use equipment is few, and technology is simple, greatly reduces cost, evoh layer material price is cheap, and has good barrier and biological degradability, inexpensive, product thickness after compound is only below 0.2mm, adhesive-free, environmental protection difficult drop-off, barrier property is good, intensity is high, and holistic cost is cheap.
Accompanying drawing explanation
Fig. 1 is overall sectional structure chart of the present utility model.
In figure, 1PE layer, 2HDPE layer, 3EVOH layer.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment in the utility model is described in further detail.
As shown in Figure 1, the high-low temperature resistant high-barrier food packaging safety sealed membrane that the utility model relates to, comprise PE layer 1, also comprise blending and modifying polymeric layer, described blending and modifying polymeric layer is made up of HDPE layer 2 and evoh layer 3, by blending technology, HDPE layer 2 and evoh layer 3 are polymerized to one, described blending and modifying polymeric layer utilizes dry compound machine to be compounded on PE layer 1.
As further technical scheme, the evoh layer 3 in described blending and modifying polymeric layer utilizes dry compound machine to be compounded on PE layer 1.
Described HDPE layer 2 thickness is 0.03mm, and described evoh layer 3 thickness is 0.01mm, and described PE layer 1 thickness is 0.10mm.
In the utility model, HDPE layer 2 in described blending and modifying polymeric layer is continuous phase, evoh layer 3 is decentralized photo, utilize the high barrier of evoh layer 3 and the high tenacity of HDPE layer 2, between HDPE layer 2 and evoh layer 3, utilize bulking agent to improve the character of two-phase interface tension force, pass through melt extrusion technology, directly extrude the blending and modifying polymer blend membrane of the blended obtained function admirable of HDPE layer 2 and evoh layer 3, utilize the mechanical performance that PE layer 1 is good, employing dry compound machine realizes the compound between rete, realizes high barrier and the obdurability of sealed membrane.
The above, be only better possible embodiments of the present utility model, and be not used to limit scope of the present utility model.
