The right packaging will keep
your oil free from contamination, even after the pack has been opened.
For example EVA’s tin pack comes with a special plastic cap which will
keep the tin closed even after it has been unsealed. This ensures that
the quality of oil is not compromised even after the seal has been opened.
Similarly, EVA pouch and PET bottle also have re-sealable caps.
Moreover, these packs are easy and convenient to open. No tin openers,
scissors, cutters etc. are needed for opening EVA tins and pouches.
