Tube Cap Options
BodyPak tubes are available with standard caps such as screw on and flip top caps. However, alternative options can be sourced at your request.
Tube Diameter
A variety of diameters are available as standard and range from 15-60mm, however any length can be cut which will determine a custom capacity. Proportionally, a diameter of 15mm would be used with small tubes (i.e. 10ml) whereas a diameter of 60mm is commonly used with larger tubes (i.e. 300ml). Please call us with your requirements. A full list of standard diameters are as follows: 15, 16, 18, 19, 22, 25, 30, 35, 38, 40, 45, 50.
Material & Thickness
Our flexible tubes are produced in either monolayer or 5-layer construction, the standard being a monolayer in Polyethylene (PE) material.
The monolayer PE material can be offered in various blend ratios of HDPE and LDPE to provide different properties in certain applications. For example a greater proportion of HDPE provides a tube with greater stiffness, and conversely a greater proportion of LDPE provides a tube with greater flexibility. HDPE also has a higher barrier to gases and a higher chemical resistance than LDPE.
The 5-layer tubes provide even greater barrier resistance than monolayer tubes. The inside and outside layers are LDPE with the centre layer made in EVOH (Ethylene Vinyl Alcohol), separated by two adhesive layers. An extra cost is incurred when upgrading from monolayer to 5-layer tubes.
