MATERIAL GUIDE / CORE POLYMER FAMILY

Flexible polyethylene

Polyethylene materials commonly associated with film, sacks, wrapping and flexible packaging.

UNDERSTANDING LDPE / LLDPE

Start with the material.
Build the specification.

LDPE and LLDPE are polyethylene materials used across flexible products. Film streams vary according to their source, composition, printing and condition. A clear description should identify polyethylene film and disclose any laminated layers, labels or other materials present. Supply enquiries should describe the intended conversion process, appearance and technical requirements. This profile is general material guidance: the appropriate route for a particular film stream depends on its composition, preparation and the agreed specification.

Typical applications

Packaging films and wraps
Heavy-duty sacks and bags
Protective sheeting
Flexible containers

Points to consider

Known film composition and original use
Clear, coloured, printed or unprinted presentation
Laminations, labels and other materials
Moisture, dirt and residual contents
Required appearance and processing characteristics

Applications describe general uses of this polymer family. A particular recycled grade still needs to be assessed against the intended process and end use. Material acceptance and supply availability are confirmed for each enquiry.
