We have a lot of experience with sizing cork lids and generally the way we do it is to work with our extensive range of samples with a client\u2019s and try out a range of different sizes. If nothing fits from our samples, then we will make a new sample just to make sure that we get the fit exactly right. This is why we strongly recommend that all new clients send us a sample of their jar, because a small difference of 1mm in the diameter can make a big difference to the fit and working from a drawing is never the same as trying out samples. One thing worth noting is that we never supply clients from stock cork lids, so every lid we produce is made to exactly fit our client requirements.<\/p>\n\n\n\n
The final issue to consider is the kind of cork that is used \u2013 generally we make our lids from standard grain agglomerated cork (0.5-4.0mm), but occasionally we get asked for micro-agglomerated cork, where the grains of cork are tiny and more bonding agent is used to make them; as a result, micro-agglomerated cork is less compressible than standard agglomerated cork, so the lids have to be made fractionally larger. Generally, we always advise that you use standard grain however, as it less expensive, has a more natural, \u2018organic\u2019 look to it, compresses better and is more environmentally friendly.<\/p>\n\n\n\n
