Hi. I work at the Museum of Design in Plastics and we are putting together a loan box for the different plastics manufacturing techniques. We would like to include some samples of raw plastic pellets but we do not want them to be eaten or lost! We have experimented with petri dishes and sealing them shut with both gorilla glue and tape. However, the glue looks messy and with the tape we have found that we can still get into the pots. We have got hold of some medical pots with a tamper-proof seal but these can also be opened. Does anyone have any experience of sealing small pots shut permanently and if so, can you recommend what we might try/use? Any advice gratefully appreciated and thank you in advance.
