Comparison of repellent mesh bags and paper bags

Paper bags Repellent mesh bags

• Poor ventilation and light transmit. • Good ventilation and pervious to sunlight .

• Poor heat dissipation. • No heat accumulated problem.

• Easy broken in the raining and has rain accumulation problem.

• Mesh bag don’t keep rain. Repellence mixed in plastic and won’t be flushed off by rain.

• Water proof paper become worse ventilation and light transmit.

• Mesh designed make fruits grow in nature.

• Only one time used. • Can be used repeatedly to save cost.

The difference between repellent and conventional mesh bags.

Repellent mesh bags repel fruit fly by repellent agent.

Conventional mesh bags don’t contain repellent agent.

Recommendations

Mesh bags keep fruits in nature color. Light color fruits

such as: loquat ,we strongly suggest don’t use.

Fruits on orchid side, please keep leaves as shelter to

prevent from sun burn problem.

Keep the same growth condition after wrap, No dormancy problem.

Repellent mesh bags are mainly for fruits fly but not for all insects.

Validity is till the bags fade into different color.

Sterilization is strongly suggested for repeated use.
