If you pack flower or concentrates, buyers and some state rules will ask whether the package is child-resistant. This is the short version we give brands who are buying glass from Vinylpac in Saco — not legal advice, just how the jars on our floor are specced.
PPPA vs ASTM D3475
The Poison Prevention Packaging Act (PPPA) is the federal idea: certain household substances have to be in packaging that is significantly difficult for children under five to open, and not difficult for adults. Cannabis is mostly regulated at the state level, so the test labs and buyers usually point at ASTM D3475 — the standard specification for child-resistant packages — rather than a single federal cannabis rule.
A lid that “feels tight” is not the same as a certified CR package. The push-and-turn (or equivalent) has to be tested as a system with that container.
Which Vinylpac jars are child-resistant
- Miron Eris 5ml — certified CR lid, 3-layer PHAN liner. Default concentrate / hash-rosin puck.
- Miron Saturn 150ml — CR lid on the quarter-ounce violet jar.
- 4oz gloss black — CR lid on the eighth-ounce (40 dram) flower jar.
- Miron Ceres 5ml — not CR. Slim cosmetic puck for salves and non-CR 5ml fills.
Labels cannot break the lid
A wrap that glues the cap to the glass defeats CR. That is why our 5ml Miron wrap is perforated — the lid still turns. Top stickers sit on the lid, not across the thread.
We print those labels in the same building. Buy the jars or order the label sets. For a mixed case, email info@vinylpac.us or call 207-272-8762.
