A label that did not stay on

The definition

Securely attached means a label can reasonably be expected to remain affixed during the foreseeable conditions and period of use. For a janitorial jug that means wet hands, spilled concentrate, a damp floor and months of handling.

Why HDPE makes it harder

It has low surface energy, so adhesion is harder to achieve than on glass or coated board. Every container on this shelf is HDPE, which makes this a shelf-wide consideration rather than a one-off.

And the chemistry attacks the label

Alkaline concentrate running down the outside of a jug lifts facestock and smears ink. On a product whose directions for use are a required label element, that is a compliance failure and not a cosmetic one.

Directions for use are the part that matters most

They are what tells a worker the dilution and the precautions. A label that has become illegible has removed exactly the information the rule required it to carry.

Test it the way the rule frames it

Foreseeable conditions and period of use. So a filled jug, handled wet, with concentrate wiped down the side, checked after a month. That is a cheap test and it matches the standard’s own words.

Consider direct marking or a tougher facestock

A molded or printed-on marking has nothing to lift. Failing that, a synthetic facestock with an adhesive specified for low surface energy plastics and wet application is the ordinary answer.

And remember the second copy

For bulk containers remaining in the user’s custody, a copy of the labeling with all directions for use goes in the immediate vicinity of the discharge control valve. That copy lives in the same wet environment.

Treat it as a packaging specification

Facestock, adhesive, ink and the container surface are four decisions and they are usually made by four different suppliers. Specifying them together, against a wet alkaline environment, is what turns a recurring complaint into a solved problem.
