Rizo crossing bags for research purpose 株式会社リーゾ

We designed Rizo crossing bags based on breeding researchers' supervision and cooperation.
The trigger was the voices from our customers who are researchers suffering from self-made glassine paper crossing bags, such as:

"It sticks to inflorescences when it's wet."
"It's poorly breathable, and the inside gets moldy."
"Since it's acid paper, the pre-made stock becomes deteriorated easily."
"Sometimes they don't become bag shape because of poor amount of glue or excessed glue inside that closes the opening."
"It takes time and effort to make them by ourselves, but if we order them, they become expensive."

We use nonwoven fabric made by quite thin polyester instead of glassine paper.

This nonwoven fabric has features:、

・Thin and light (Normal type=40g/m2, Thin type=20g/m2）
・Has fine meshes and doesn't make pollen pass through
・Allows moisture and air go through
・Transmits light well
・Doesn't lose strength even it's wet and can keep the space inside.
・Doesn't break in water
・Dries fast
・Thermal adhesion is possible with a sealer.
・You can write letters with a felt-tip marker or ballpoint pen.

　
We form this nonwoven fabric into different kinds of crossing bags, by using thermal adhesion, not by using glue.
We recommend our high functional research dedicated crossing bags for your important pollination experiments.
