Labelling
CAN/CGSB-51.33-M89 requires that labelling of the product or packaging must be in conformance with Section 7.1, namely with the following information displayed:
- manufacturer’s name and address,
- trademark,
- the phrase “sheet vapour barrier,”
- width, length, area of the sheet,
- type,
- the phrase “complies with CAN/CGSB-51.33-M89”; and
- average thickness of the material (only for material made entirely of plastic film).
- the associated CCMC number
Where applicable, the product must bear additional information as below:
- any necessary user safety information, unless a separate information sheet is provided; and
- any additional information required by applicable acts and regulations.
