Thin Wall Packaging

High flowability and good mechanical properties

As the market leader in the thin wall packaging consumer area, Borealis offers a full product portfolio based on our Borstar® and Borealis Nucleation Technology (BNT) proprietary technologies.

Our customers and value chain members benefit from excellent material performance and advantages including cost effective processing, down gauging possibilities and quality assurances for a broad range of material applications.

Clear benefits with an impact

  • High flow BNT materials, which can be processed and cooled quickly reducing cycle times
  • Good balance of mechanical properties, including stiffness and impact
  • Excellent organoleptic properties (no taste, no odour)
  • High transparency with random copolymers

Proven technology for sustainable results

Our materials, based on Borstar® and BNT, make it possible to combine the three critical requirements of high flowability, good mechanical properties and in the case of random copolymers, high transparency. We are one of few companies offering a full product portfolio for the thin wall packaging market; organoleptic high flow blocks (MFRs up to 100), organoleptic and transparent high flow randoms (BorPure™ grades) and also specialties, e.g. transparent material with good low temperature impact (Borpact™ SH950MO) for ice cream packaging.

Increasing value by working together

Borealis works closely with value chain members to enable down gauging and increase productivity. For example, high flow materials with BNT can create a cycle time reduction of up to 20% for the convertor, depending on the part and application, resulting in energy and cost savings. Our customers have been able to down gauge their design due to the higher flow and improved mechanical performance in several instances.

Functional and environmentally friendly plastics

Borealis offers a wide range of recyclable polyolefin consisting of high density polyethylene (HDPE) and polypropylene (PP) grades for blow moulding applications.

Lightweight and robust plastics can help make packaging forms such as bottles more consumer friendly than traditional materials like glass and aluminium. Yet the material demands posed by manufacturers and consumers alike are varied and complex. Converters require highly reliable and cost-efficient materials which can be used with a variety of production techniques, including extrusion blow moulding (EBM), injection blow moulding (IBM) and injection stretch blow moulding (ISBM). Materials must:

  • Provide for easy processing
  • Enable downgauging
  • Offer good mechanical properties, including ideal balance between impact/stiffness as well as stiffness/chemical resistance
  • Be suitable for applications requiring high stiffness and top loads

Manufacturers, brand owners and consumers also demand excellent organoleptic properties.

Transport Packaging

Durable solutions across applications

Borealis technologies enable transport packaging solutions that meet key market demands.

Returnable Transport Packaging (RTP) involves packaging solutions used for the transport of goods that are designed for reuse within a supply chain. Typical RTP items include bins, boxes, trays, pallets, crates and more. Widespread industry acceptance of RTP solutions has spread from the automotive to other sectors, including food & beverage, pharmaceuticals, consumer electronics and more. For both manufacturers and businesses, switching from traditional packaging forms to RTP can help achieve cost savings. What is more, using RTP satisfies demand for increased environmental sustainability, as reusable solutions mean less waste. Finally, RTP solutions are often easier and safer to handle in transit and storage, thus contributing to overall employee safety.

Providing durability for RTP

Borealis supplies a range of polypropylene (PP) grades for injection moulding (IM) techniques which fulfil the most important criterion for RTP: durability. Plastic materials need to be able to withstand handling and stacking during transportation and storage. On the shelf, they must be resistant to wear and tear and retain their visual appeal when used as point-of-sale displays. Thanks to our proprietary Borstar® technology and Borealis Nucleation Technology (BNT), we have optimised our grades to meet such market demands.

Optimised results thanks to Borealis Nucleation Technology

Grades manufactured with BNT exhibit a highly uniform crystalline structure during cooling, rapid solidification for earlier demoulding, and higher output in the IM process. RTP items manufactured using BNT offer the following advantages for the value chain:

  • Production output increase through reduced cooling time and high flowability
  • Good balance in mechanical properties (stiffness/impact)
  • Limited impact of colouring on dimensional stability
  • Superior stackability through high stiffness and excellent creep properties
  • Very good impact resistance translates into more durability during transportation and storage
