Frozen food packaging is one of the most demanding packaging applications. Films employed must have excellent physical properties at low temperature, along with good sealability and generally good printability.
Key benefits with Borstar Enhanced Polyethylene:
• High mechanical strength – excellent impact resistance at low temperatures from 23deg C down to –40degC
• Down-gauging – better or equal mechanical strength with thinner Borstar Enhanced PE films compared to conventional PE
• Stiffness – high speed packaging
• Matt surface – low blocking, easy to open film
• Low migration – no taste and odour contamination

The packaging of dried foodstuff such as cereals, noodles, crackers and biscuits requires a good moisture barrier and sealing properties to prevent the product from losing its crispiness, as well as general product protection and good display of the product.
Dry food film is often used in a form, fill and seal (FFS) operation and requires a sealant that peels easily when the bag is opened.
Key benefits with Borstar Enhanced Polyethylene:
• Stiffness – packaging speed
• Matt surface – easy opening/ filling
• Impact/ puncture resistance – pack integrity
• Low temperature resistance – high integrity at frozen conditions
• Stiffness / impact balance – down-gauging
• Low additive levels – compliance to food regulations, less problems in lamination
• Low migration – low taste and odour

PE Films, mono and co-extruded, are used for a variety of stand up pouches as the main component in duplex and triplex laminated structures.
PE based stand up pouches are typically used for packaging of beverages, non-retorted food and non-food products.
Key benefits with Borstar Enhanced Polyethylene:
• High ESCR – shelf life and no breakage
• Increased Stiffness – pouch rigidity and handling
• High Toughness – cost savings and design freedom
• High Seal strength – less risk of product spoilage
• Matt Surface – ease of conversion, alternative aesthetics and filling

Plastic envelopes and pouches have been successfully used for courier shipments, direct mail and moneybags.
This is due to the beneficial properties of plastics like repelling of water, toughness, security aspects, efficient production etc.
Key benefits with Borstar Enhanced Polyethylene:
• Increased stiffness – pouch rigidity and handling, potential for down gauging
• High Toughness – high protection and security
• High seal strength – less risk of breakage
• Matt Surface – easy write-on, reduced transparency, ease of conversion

Liners are used in a variety of formats ranging from sheets and pouches to converted bags in sacks, boxes, barrels and containers.
Their key purpose is to provide a protection and a barrier between the product and the outer container.
Key benefits with Borstar Enhanced Polyethylene:
• An excellent combination of high impact and seal strength
• High seal strength reduces the risk of package bursting during various stages of packaging life – from filling, to transportation, to end-use
• Matt surface – ease of installation and opening
• Increased stiffness – film rigidity and handling with potential for down-gauging

The use of shrink films has vastly improved the transportation and storage of food products.
Shrink films can be used to protect and display products at retail outlets. Collation shrink films are typically used for drinks cans, foods and pet foods.
Shrink films help to keep a product or group of products separate from others in the form of an easily transportable unit, or help prevent the product from affecting its surroundings and vice versa.
The film surface also provide a medium for brand messaging/ advertisements.
Key benefits with Borstar Enhanced Polyethylene:
• Very low hot shrink force - no hole burning.
• Very high cold shrink force - collation and holding forces.
• Balance of strength, toughness and stiffness - stability and stack-ability during transport and handling, improved film integrity, less film puncture with sharp edges, possibility to down-gauge.
• Matt surface - easy to open film, easy to apply onto e.g. pallets.

Shipping sack production is a major area for the film converting industry. The growth of global trade has led to higher demand for transportation of goods, which in turn creates opportunities for protective and heavy duty shipping sacks.
Heavy duty shipping sacks are used for a variety of goods, including bags for polyolefins. In the Middle East and Asia Pacific regions, filling lines for heavy goods such as plastic pellets, pigments, fertilizer, sand, fish food, are tending more towards the form-fill-seal (FFS) system. This system calls for properties such as good sealing, toughness, rigidity, hot content capability and shape retention.
Borstar enhanced polyethylene is the only PE material available in the market today which can combine excellent processing characteristics with final film toughness.
Other key benefits of Borouge’s Borstar bimodal enhanced polyethylene for heavy duty sacks include:
• Excellent combination of high impact and seal strength, thus reduces risk of package bursting during various stages of package life – from filling, to transportation, to end-use
• Superior load retention and minimize deformation of package in use
• Material savings and lower costs
• Shorter production time per bag unit
• Reduced transportation costs
• Reduced environmental taxation

Polyethylene can be used in a variety of agricultural films such as greenhouse tunnels, mulching and silage. Crop yield and quality is directly influenced by choice of film structure.
Key benefits with Borstar Enhanced Polyethylene:
• Increased stiffness – good load bearing
• Matt surface – haze prevents crop damage protection, light scattering enhances yield and quality of red coloured products
• Toughness – less risk of breakage in tough weather conditions
• ESCR – resistance to crop treatment
