Protection for plastic fabric in containers against ultra-violet rays

摘要

Protecting plastic containers from the effect of ultra-violet radiation when the fabric containers are used for bulk goods, e.g. flour. There are a number of threads (4,5) which have been protected against penetration by ultra-violet rays in both the transverse and the longitudinal direction. These threads are in addition to unprotected threads. Alternatively, the fabric sites containing a seam are protected against ultra-violet radiation. Protection can be through colour or covering strips in the seam areas.
