Applications

BRALEN+ FB 4-31 is suitable for production of non-slip blown films, surface protection films, cast films. Recommended film thickness is 0.015 to 0.040 mm. This grade can be used also for extrusion coating and injection molding applications.

Processing

BRALEN+ FB 4-31 can be used in conventional extrusion machines. Recommended processing temperatures are 150-190 °C.

Recycling

Polyethylene resins are suitable for recycling using modern recycling methods. In-house production waste should be kept clean to facilitate direct recycling.

Regulatory & Compliance

Certifications & Compliance
Reach Statement

Polymers are exempt of REACH registration. However, their raw materials which mean monomers and relevant additives have been registered. SLOVNAFT, as. is committed to fully respect legislation and will only use REACH compliant raw materials. At this point in time LDPE BRALEN+ does not contain any substances specifically identified as SVHC at levels greater than 0.1%.

Packaging & Availability

Packaging Type

Storage & Handling

Storage and Handling

Pellets are packed in 25 kg PE-LD bags and transported on stretch wrapped pallets at eligible load of polymer 1375 kg. Heat treated pallets are available as well. We use adhesive between the bags in order to avoid their slipping. Pay attention to this fact during the removing of the bags from the pallets. The prefered method is to lift the bag at first without rotation. Transportation in a road silo or rail silo is also available.

Since polyethylene is a combustible substance, the fire safety rules applicable for combustible materials in warehouses and store rooms should be observed.

If polymer is stored in conditions of high humidity and fluctuating temperatures, then atmospheric moisture can condense inside the packing. If it happened, it is recommended the pellets to be dried before use. During the storage polyethylene should not be exposed to UV radiation and temperatures above 40°C. Producer does not take responsibility for any damages caused by adverse storage.
