  1. bpi.agri is a leading global supplier of innovative agricultural films: • Silage Stretch Film • Silage Sheets • Silage Bags

  2. bpi film is used to wrap more than 50 million bales in over 50 countries every year

  3. Operations Overview

  4. Leading Production Facilities

  5. How it all began….. • In the early days of bale wrapping most bale wrap was made up of a single layer construction • Then in 1986 BPI pioneered “co-extrusion” which was to change the future of the manufacturing of silage stretch wrap

  6. Extrusion Methods

  7. Single Layer Extrusion

  8. A Multi Layer Extruder • A co-extruder works on the same principle as the mono layer machine, but a minimum of three times over to form a multi layer sheet

  9. A new 5 Multi Layer

  10. Quality

  11. Quality • Throughout the production process we evaluate the following product properties and tests: • Dart drop test • Weather testing • Winding tension • Tear strength • Tensile Test

  12. Quality • Holes and windows • Tack tests • Bale wrapping test • Opacity

  13. Quality Accreditations • BS EN ISO 9001 Quality Assurance Standard • 14001 Environmental Standard • SP (01) (02) (03) (04) Swedish Quality Standards

  14. Development Partners Working closely with Dow Chemicals Undertakes research initiatives with IBERS Universities Complies with rigorous Swedish SP Standard

  15. Product Overview

  16. Product Range • Silage Stretch Wrap • Silage Sheets • Silage Bags

  17. Product Overview • Silage Stretch Wrap Colours: • Black • White • Green • Silage Stretch Wrap Widths: • 250mm • 360mm • 500mm • 750mm

  18. World’s first multi layer balewrap • Over 20 years experience • Global market leader • Sold in 58 countries across 6 continents

  19. Multi-layer construction for superior strength • High tack level eliminates long tails • Superior tack level for excellent sealing • Uniform stretch with no striation weakness • UV sunlight protection for all climates

  20. Wrapping Process

  21. Crop Preparation The crop must be suitable for making good silage/haylage It should be at the correct growth stage Over-mature stemmy crops do not produce good results! Choose a favourable period of weather Produce a full-width swath of oblong section and uniform depth and density Aim for 40-50% dry matter (DM) at baling, and up to 60% for haylage Do not wrap bales which exceed 60% DM Make well-shaped bales of uniformly high density Avoid soil contamination

  22. Types of Bale Wrappers

  23. New Generation Bale Wrappers

  24. Bale Wrapper Maintenance

  25. Bale Wrapper Preparation • Set wrapper and install film as per manufacturers’ instructions • Follow bpi.agri’s Ten Top Tips of Bale Wrapping available to download from www.bpiagri.com. Hard copies always available from your bpi.agri contacts • Better Balewrapping DVD also covers this subject and is also available from your bpi.agri contacts

  26. Bale Wrapper Calibration Align film with bale centre to achieve correct overlap

  27. Bale Wrapper Calibration 25 mu film should be applied at 55-70% stretch on round bales and 55-60% on square bales, depending on climatic conditions Two marks applied 10 cm apart on the reel should then be 15.5 – 17cm apart when on the bale

  28. Bale Wrapper Calibration How to calculate film usage The number of bales that can be wrapped from a single roll of bale wrap can be accurately calculated, provided the following points are adhered to: THE BALE SIZE IS 1.2m X 1.2m AND OF UNIFORM SHAPE THE WRAPPER IS CALIBRATED FOR THE CORRECT NUMBER OF TURNS 4 film layers 16 turns (750mm) 6 film layers 24 turns (750mm) THE FILM IS ACCURATELY AND CORRECTLY STRETCHED TO 70%

  29. Bale Wrapper Calibration If all the parameters are correct (bale size, film stretch of 70% and correct number of bale revolutions) then the following figures will always be achieved. Any variation to the above parameters will cause numbers to differ. Given a standard bale size of 1.2m x 1.2m, applying film at 70% stretch using the correct number of turns for the film width used 16 turns for 750mm for 4 layers of film) the calculations are as follows:

  30. Bale Wrapper Calibration A = BALE CIRCUMFERENCE (sum length of all four sides of the bale) B = TURNS OF THE BALE C = FILM LENGTH AFTER STRETCH (film roll length plus 70%) Multiply A by B and divide into C. 2,550m(1,500m +70%) 33.2 bales per roll

  31. Bale Wrapper Calibration If however your stretch % is only 55 % then 750mm 2325 m(1,500m +55% ) 30.2 bale per roll CURRENTLY AT 55% STRETCH WHICH MOST BALERS ARE SET AT ARE ALREADY ACHEIVING 3 MORE BALES PER ROLL WITH SILOTITE! SO WHEN CORRECTLY SET UP SILOTITE SHOULD BE R 1,50- R 3 CHEAPER PER BALE THAN ANY OTHER FODDEWRAP ON THE MARKET EVEN THOUGH IT IS MORE EXPENSIVE PER ROLL

  32. Bale Wrapper Calibration Depending on % stretch and temperature

  33. Bale Wrapper Calibration Count number of turns to completely cover bale in film. Add 1 extra and double this figure for 4 layers. Add 1 extra and triple this figure for 6 layers. E.g. 8 turns to completely cover + 1 = 9 x 2 = 18 turns for 4 layers.

  34. Essential Bale Wrap Properties During The Wrapping Process • Must have even stretch • Resistance to tear during elongation • Correct tack level • Not over elastic so that film is over stretched and too thin when on bale

  35. Essential Bale Wrap Properties After The Wrapping Process • Needs to have a “memory” and retain elasticity • UV protection to stop degradation • Strength properties to resist puncturing and tearing of film as well as impact damage • Adhesive properties to maintain long term sealing • Low oxygen permeability

  36. Handle Bales with Care

  37. Potential Balewrapping Issues

  38. Common Problems • Operator Error • Spiral Tearing • Aquaplaning • Film Breaking • Holes in film on bales • Film splitting on bales • Uneven overlap on bales • Rodent damage

  39. Spiral Tearing

  40. Film Striations

  41. Air Bubbles

  42. Tack Build-up on PSU Rollers

  43. Aquaplaning

  44. Resolving Aquaplaning

  45. Holes in Film on Bales Bird Damage Bramble Damage Handling Damage Rodent Damage

  46. Bales Splitting Not enough film – uneven application

  47. Worn Belts causing uneven overlap

  48. Roll Identification

  49. Summary • Always handle rolls of film with care • Load film in the correct way • Keep PSU rollers clean from tack build up • Align film with centre of bale • Calibrate number of turns required • Check film for correct stretch & neck down • Ensure wrapper is properly maintained for optimum film application
