At Gunze, we have the type of film called MV2, which is often used for fresh vegetables such as pre-cut vegetables and bean sprouts.
By the original multi-layer technology, it has the advantage of high seal strength with stability.

Why is stable high seal strength required for the packaging of fresh vegetables?
The reason is "to preserve the freshness" and "to improve the extraction rate".

(1) Freshness preserving film 
　Many fresh vegetables change color on contact with the air, and the shelf life is not long.
　Especially when the seal leakage occur, the amount of oxygen on contact with vegetables will increase, and facilitate deterioration.  
　By using MV2, it can prevent from the oxygen coming in, and can preserve the freshness of the vegetables.

 

(2) Improving extraction rate
　When the bagmaker machine is used, the bottom of the film that doesn't have strong enough hot tack, may fell out during the filling. 
　The product (vegetables) which fell out have to be discarded since it cannot be used. 
　Recently, the demand of the pre-cut vegetables is getting higher, so the amount of the pre-cut vegetables contained in one packaging
　will increase. This is the reason why the necessity to prevent the bottom of the film falling out during the filling is getting bigger.
　Therefore, the range of the sealing will be wider because of the low temperature sealing strength. MV2 contributes to the productivity
　improvement by keeping the stable strength.
　
For the details of MV2, please refer to the product information.
　We will be proceeding the freshness preserving proposal using MV2.
