Health
and safety data sheet for Polypropylene Strapping
supplied by Williams Packaging Limited.
Food Contact Status: Polypropylene strap is manufactured
and sold for secondary (not primary) food packaging
contact.
Composition
Polypropylene Homopolymer (approx 95-97%)
Chalk (approx 2-3%)
Colour Pigments (approx 1-2%)
Thermal Behaviour + Combustion
Melting Temperature 165_C - 170_C
Decomposition – When heated above its melting
point polypropylene may evolve fumes at approximately
225_C. Decomposition and Oxidative Pyrolysis will
occur at 300_C when Carbon Dioxide (OES-TWA-5000PPM)
Carbon Monoxide (OES-TWA-50PPM) Formaldehyde (MEL-TWA—2PPM)
and Acrylaldehyde (OES-TWA-01PPM) may be evolved.
Carbon Monoxide cannot be detected by smell but
the irritant effect of Formaldehyde and Acrylaldehyde,
which is noticeable at OES limits, provides a good
indication of excessive limits.
It is recommended that the continuous operation
of the heat-sealing process for polypropylene be
carried out in well-ventilated conditions.
Auto Ignition Temperature 380_C
Extinguishing Media – Foam, Carbon Dioxide
Dry Powder, Water Spray
High Tensile Polypropylene
Strapping
General Information
Polypropylene strapping is a lightweight flexible
tape designed for use in securing applications.
It is available in a wide variety of sizes and tensile
strengths and when in use it is important to ensure
that the correct grade of strap has been selected.
Good Housekeeping
To avoid accidents caused by tripping and slipping,
it is important that all packing and unpacking areas
are maintained to a high degree of tidiness. Loose
straps should never be allowed to remain on floors;
all old packaging material should be placed in a
disposal container immediately.
Storage
Polypropylene should be stored between -5_C and
+40_C. Long term exposure to direct sunlight will
result in brittle failure. Where possible store
in original containers away from sunlight.
Incompatible substances:
None
Skin Contact
Polypropylene strapping in not considered a skin
irritant but, being fairly hard can have an abrasive
effect on the skin.
Protective Clothing:
Not required
Toxicity
Polypropylene is chemically unreactive and may be
regarded as insert. However, smoking, eating and
drinking should not be allowed in working areas.
Ingestion
Although polypropylene may be regarded as harmless,
ingestion should be avoided |
