  1. Blow Moulding Process & Barrier Containers Part3 Multilayer coextruded containers

  2. Advantage of multimayer bottles • - Strength and rigidity • - Aluminum seal weldable • - Printable and labeling • - Use of R-material (middle layer) • - Esthetic (gloss) • - Chemical resistance • - Barrier layer • food/beverages: oxygen, light • cosmetics: active chemicals, oxygen • agro: active chemicals, oxygen

  3. BOTTLE WALL Water Fragrancies Oxygen Water Smell Bad smell Function Barrier layer function: reduce migration of gases through the bottle wall

  4. Coefficientofpermeability K- Coefficient of permeability for commercial plastics

  5. Barrier performance

  6. Selection • Polymer and structure selection for barrier containers (1) • Data related to: • Polymer compatibility/adhesion to other polymers • Barrier coefficients • Aroma migration data • Water absorption • Chemical and swell resistance to organic solvents, oils and fats • Chemical resistance to agrochemical active components • ESCR at different °T are provided normally by polymer, barrier resin and adhesive manufacturers.

  7. Selection Polymer and structure selection for barrier containers (2) Brand owners in the food, agro, pharma and cosmetics activity have to issue own customer specifications, which has to identify the container design, weight and structure in terms of polymer selection, including the barrier resin. The blowmolder has to agree with the brand owner about feasibility, cost, timing and container performance.
