MDPE combines the characteristics of low and high density polyethylene. Bottles are less translucent than LDPE but more flexible than HDPE. Like LDPE, MDPE is glossy when produced in colours.
This plastic is ideal for liquid storage tanks such as water butts and oil tanks.
MDPE bottles are the favourite choice for any kind of ‘squeezy’ bottle as they come with both pointed nozzles and caps, so you get all the benefits of flexibility. Cake decorators love to use them for piping icing and then storing the leftovers, this saves a lot of wastage.
MDPE has good shock and drop resistance properties. Stress cracking resistance is better than that of HDPE. MDPE is typically used in gas pipes and fittings, sacks, shrink film, packaging film, carrier bags, and screw closures. The Plastic Bottles Company is based in Cumbria, in the UK.
