Linear Low Density Polyethylene (LLDPE) is blended form of LDPE. This form of polyethylene tubing provides much more flexibility, tensile strength, and more conformability. LLDPE tubing is also the most flexible of the plastic sheeting films, while providing increased softness and pliability. LLDPE is used for numerous applications and can be blended into other films to give them more flexibility and extra strength.
Pneumatic LLDPE tubing’s greatest advantage over standard low density polyethylene (LDPE) is its superior environmental crack resistance, or ESCR. Environmental stresses that can affect the longevity of LDPE tubing include chemical exposure, aging, connection to barb-type fittings, and high-vibration connections with compression fittings.
At Freelin Wade our pneumatic LLDPE tubing can withstand 500-plus hours of exposure to IGEPAL solution, per ASTM D-1693 ESCR tests. LLDPE tubing also resists cracking when used with compression or push-to-connect fittings. All colors of Freelin-Wade LLDPE tubing comply with FDA regulation 21 CFR 177.1520(c) for food contact applications. Contact us

Pneumatic LLDPE Tubing Features & Benefits
LLDPE ultimately provides greater flexibility and greater stretch consistency than LDPE materials, which is how it can withstand heavy impact damage. When hit with a great amount of force, LLDPE can flex and bend into the impact and then snap back into place, which provides better consistency than that of other types of softer plastics.
When compared to low density polyethylene (LDPE), linear low density polyethylene tubing (LLDPE) manufacturing products are extremely popular due to their high tensile strength and excellent impact and puncture resistance. LLDPE plastic products also provide good chemical resistance and protection against stress cracking. Some of the other features and benefits associated with LLDPE tubing, include:
- Greater tensile strength than LDPE tubing
- Higher burst pressure
- Superior stress and crack resistance
- High puncture resistance
- Impermeable to gasses and moisture
- Tasteless and odorless
- Superior dielectric properties
- Available in black, gray, red, green, blue, yellow, orange, clear, and purple

Linear Low Density Polyethylene (LLDPE) vs Standard Low Density Polyethylene (LDPE)
The main difference between LLDPE and LDPE plastic material can be observed at the molecular level. The cellular structure within LLDPE tubing is tighter than that of LDPE, which makes it stronger and more pliable than LDPE. LLDPE tubing’s greatest advantage over standard low density polyethylene (LDPE) is its superior environmental crack resistance, or ESCR. Environmental stresses that can affect the longevity of LDPE tubing include chemical exposure, aging, connection to barb-type fittings, and high-vibration connections with compression fittings. LLDPE is also more flexible than standard LDPE plastic material, while providing increased impact resistance.
