The quality of fruit growing bags directly affects the effect of bagging. Improper use of the bag will not only improve the quality of the fruit but also seriously damage the fruit, as well as cause some pests. So let’s take a look at how to identify the quality of fruit bags!

 

1.Use the light penetration method to test the shading of fruit growing bags 


Put a fruit growing bag on the opened incandescent bulb and observe the light penetrating the fruit growing bag. If the light penetrability is poor, the fruit growing bag has good shading properties; otherwise, the fruit growing bag has poor shading properties. 

The shading of fruit growing bags determines the speed and degree of fruit coloring after unpacking.

2.Test the air permeability of the fruit growing bag with the cup mouth method 


Seal the fruit growing bag on the mouth of a cup full of boiling water. If the paper surface is airy, it indicates that the fruit growing bag has good permeability; if it does not air, it indicates that the fruit growing bag has poor air permeability. 

The air permeability of the fruit growing bag affects the occurrence of fruit diseases and the smoothness of the fruit surface to varying degrees. 


3.Test the waterproofness of fruit growing bags by water pouring method 


Pouring the fruit growing bag with water. If the water rolls on the fruit growing bag, it indicates that the fruit growing bag has poor water absorption and good water resistance; if the water is dispersed on the fruit growing bag, it indicates that the fruit growing bag has strong water absorption and poor water resistance. 

The water-resistance of the fruit growing bag can determine the strength of the fruit growing bag withstand rain erosion, determine the service life of the fruit growing bag, and also affect the infection of the fruit by saprophytic bacteria or weak parasitic bacteria.

4. Test the strength of the fruit bag by tearing method, burning method, and hand rubbing method


Tear method: Horizontally torn fruit growing bags, the paper with stubble is wood pulp paper, which has high strength; if the tear opening is neat and there is no stubble, it is straw paper or wood pulp with less composition and low strength. 


Burning method: After burning, the paper ash will not be broken into pieces, and the paper quality is good; the paper ash will be broken and not formed, and the paper quality will be poor. 


Hand rubbing method: Soak the fruit growing bag in water for a period of time, and rub it with both hands after taking it out. If it is lint-free or rub-resistant, it means that the paper is of good quality.
