Plastic Tube Construction

LDPE

Low-density polyethylene is a thermoplastic  made from the monomer ethylene. Made in translucent or opaque variations, it is quite flexible and tough. This chemically inert, non-contaminating translucent tube meets FDA standards. LDPE tubes are cost efficient and are great for pharmaceuticals, cosmetics, personal care and food products.

MDPE

Medium-density polyethylene is a type of polyethylene  defined by a density range of 0.926–0.940 g/cm3.  Slightly stronger than LDPE, tubes made with MDPE are primarily used for pharmaceutical, industrial, personal care and food products.  Costing slightly more than LDPE, MDPE tubes are more durable.

HDPE

High Density Polyethylene is less flexible than LDPE and MDPE, but has better physical and chemical properties, and withstands sterilization by boiling. HDPE tubes are widely used for products containing, water and chemicals. High Density Polyethylene tubes are produced from raw materials which meet FDA requirements. HDPE is resistant to many different solvents and has a wide variety of applications.

 

EVOH

Ethylene Vinyl Alcohol Polymer provides very strong barrier properties and is the most recommended barrier for plastic tubes. This is ideally suited to pack cosmetics both cream & gel based, food items and specific industrial chemicals having medium to high viscosity. EVOH is a co-polymer with outstanding barrier properties to gases such as oxygen (OTR), nitrogen, carbon dioxide and helium with a very low permeability (MTR-moisture transfer rate).  EVOH is ecofriendly and can be recycled easily.
