MATERIALS USED AT CDF
Low-Density Polyethylene (LDPE)
CDF uses LDPE for a wide range of thermoformed, blow-molded and heat-sealed products. LDPE provides excellent toughness, good clarity and flexibility and stays pliable at low temperatures. In general, CDF products made from LDPE can be used from 175°F down to -40°F. This material meets FDA requirements of 21 CFR 177.1520.
Recycle Code 4
High-Density Polyethylene (HDPE)
CDF uses HDPE for a wide range of thermoformed products. HDPE provides excellent rigidity, durability and provides better resistance to most solvents compared to LDPE. In general, CDF products made from HDPE can be used from 180°F down to -20°F. This material meets FDA requirements of 21 CFR 177.1520.
Recycle Code 2
Polypropylene
For applications requiring resistance to high temperatures (as much as 300°F), polypropylene is preferred to polyethylene, although at temperatures below 35°F polypropylene can become brittle and develop flex cracks. This material meets FDA requirements of 21 CFR 177.1520.
Recycle Code 5
Anti-Static Additive
Nearly any polyethylene insert, liner or cover manufactured by CDF can be made using materials containing an anti-static additive that aids in the reduction of static build-up. Anti-static products can meet the requirements of higher standards when more additive is added.
Anti-static products have a surface resistivity of ~10 to the 11th power Ω/square.
Conductive liners are manufactured from carbon-loaded polyethylene and have a surface resistivity between between 1,000 and 100,000 ohms/square.
MIL-B-81705C
Standards require static decay and surface resistivity testing as follows: first the material must be conditioned for 24 hours at 12% +/- 3%.relative humidity. The material must meet the 2.0 seconds or less static decay time at 12 +/- 3% relative humidity at a temperature of 73°F +/- 5°F and a surface resistivity of 1012 or less according to ASTM D257. This requirement represents CDF's highest anti-stat quality and is standard for most 55-gallon DrumSaver™ anti-stat products.
NFPA-99
National Fire Protection Association standards require the material to be conditioned for 24 hours at 50% +/- 2% relative humidity prior to testing and then must meet the static decay time of 0.50 seconds or less at 50% +/- 2% relative humidity at a temperature of 23+/- 1°C.
ASTM D-257
The international, active standard that describes the methods used for testing surface resistivity under both MIL-B-81705C and NFPA-99.
Note: CDF’s anti-stat liners contain an internal anti-stat agent that is intended as an aid to reduction of static build-up. They are not designed as and should not be used as, the primary controller of static electricity in a process. CDF’s anti-stat liners should not be used in electro-static coating systems or other highly volatile areas. Please consult your safety engineer, safety consultant, or CDF if there is any question as to appropriateness of use.
IBC Films
CDF utilizes a variety of films and fitments in the manufacture of liner-bags for IBC’s. Applications may call for oxygen barriers, odor barriers, high temperature, low temperature or anything in between. Below are some of the materials available for bags and the benefit:
Flexus™ and Flexus™ HF metallocene-based polyethylene for excellent flex crack resistance and strength.
Barria™ metallized polyester provides an excellent oxygen and moisture barrier.
Barria™ P/Foil and Barria™ A/Foil films offer superior barrier properties using an impermeable layer of aluminum foil.
Tenalon™ nylon provides strong odor barrier, abrasion resistance.
Polypropylene is excellent for high temperature applications between 200 and 300°F.
Laminated Films
ChemLiner™ Code 02 Film
Code 02 film is a symmetrical structure of nylon and linear low-density polyethylene. This material provides excellent resistance to chemical permeation and degradation, with moderate oxygen barrier characteristics. It is resistant to weak acids, methanol, ethanol and isopropanol and will significantly slow the attack of weak alkalines and ketones.
Code 07 Film
Code 07 film is a foil film laminated between a layer of polyethylene and a layer of polyester. This material meets MIL-B-131J performance specifications (Barrier materials, water vapor-proof, grease-proof, flexible, heat-sealable). It has water vapor transmission characteristics of 0.002 g/100 in2/24 hrs.
Code 09 Film
Code 09 film is a foil film laminated between a layer of polypropylene and a layer of polyethylene. This material meets MIL-B-131 performance specifications (Barrier materials, water vapor-proof, grease-proof, flexible, heat-sealable). It has water vapor transmission characteristics of 0.0006 g/100 in2/24 hrs and an oxygen transmission rate of 0.0006 cc/100 in2/24 hrs.
