That sounds like the standard vacuum pack they use to seal and compress dope before sending it out. I hate what it does to the trics on the exterior of the buds. Smashes them, oil goes everywhere, and makes the stuff like peanut brittle after a while if the flower was good and frosty. However, I always prefer that stinky stuck together mess, over a bag of dry flowers. Those trics are ready to explode in smell when that chunka dope gets broken back into buds.
I never thought to just bust off a piece and put the rest in the freezer. Always went into jars for burping.
Your right. It most certainly can break some of the trichs off, just depends how far you take it.on my vac sealer I can seal it wherever. I never ever go full vacuum, unless I’m making cobs. There is a happy medium.
