Plastics and Polymers: Polyethylene Wine Bag Amelia Hogan, Kelly Ehrler, Marissa Collins, Megan Skadan
From Farm to Fork Farm: grapes picked manually/mechanically and put into macro bins (rigid PC) durable, sanitizable, subject to cracking destemmed/crushed pumped to stainless steel tanks 4 inch flex hoses (flexible HDPE) gaskets (flexible HDPE)
From Farm to Fork Inoculation: starter culture for primary fermentation Yeast: foil coated plastic, vacuum sealed (LDPE) nutrient packages: bags with plastic liner (LDPE) 2 inch hoses: (HDPE) 5 gallon buckets: (HDPE) PPE: rubber gloves, safety goggles (PC) Drain and Press Pump juice to new tank Press must:flexible plastic bladder chamber(hdpe)
Farm to Fork Blending and secondary fermentation O. Oeni bacteria added. Stored in plastic bags (LDPE) Tartaric acid and SO2 Nitrogen Barreling Wood or steel barrels Bung (HDPE or PC)
Farm to Fork Sanitation Iodine: plastic, opaque barrels (HDPE) caustic: plastic translucent barrels (HDPE) sodium percarbonate: bagged with liners (LDPE) PPE (PC &HDPE)
Bag in Box Primary Packaging: direct product contact Polyethylene Bag Portable, durable Extends product shelf life once opened Secondary Packaging: containment of polyethylene bag Corrugated cardboard box Functions as container for bag as well as a means to dispense product
Polyethylene Bladder Bag Thermoplastic polymer Comprised of hydrocarbon chains Frequent types Low-Density Polyethylene (LDPE) Medium-Density Polyethylene (MDPE) High-Density Polyethylene (HDPE) Monomer that becomes polymerized when contact is made with catalysts
Polyethylene Bladder Bag Bladder bag manufactured with LDPE Used for Bladder bags for dispensing soda, wine, ketchup, and other liquids/condiments Other uses include plastic grocery bags and film (saran wrap) LDPE Malleable, flexible, leakproof packaging Product filled via horizontal form-fill-seal
How BIB Wine is Filled (Video) http://www.youtube.com/watch? v=kwu06fmo8dc
History of Wine Cask Wine Cask original name for BIB 1965- Invented by Thomas Angove Original design required consumer to cut off corner of polyethylene bag then replace with peg 1984- Penfold Wines and Malpas patented plastic, airless flow tap
AIRLESFLO Tap Patented by Charles Henry Malpas in 1984 Nozzle comprised of 35 individual parts Exterior HDPE Interior MDPE/LDPE Function of polyethylene based tap Omit airflow into product Lengthen shelf life of opened product Provide a resealable closure Leakproof
AIRLESFLO Tap Polyethylene-Coated Metallised Polypropylene Polymer film coated with metal, typically aluminum Dispensing nozzle Polyethylene-coated Metallised Polyester Seal between nozzle and bag Aluminum coated adhesive seal Polyethylene (PE) and Polypropylene (PP) are both types of thermoplastics
Advantages Plastic Sustainability Study done in 2010 by PETRA (PET Resin Association) glass production emitted over 4,848 lbs of greenhouse gases whereas plastic only emitted 1,125 lbs. Plastic Flexibility Plastic more easily transferable, non-breakable, lightweight Takes up less space in landfills than glass bottles
Advantages Less oxidation with bag vs. bottle Polyethylene bag and tap create airtight seal, whereas cork allows in more air Bag= lasts 2 months once opened in refrigerator Bottle= lasts 1 week once opened Cost effective Typically BIB wine is cheaper than bottled wine Peter Vella Bag (6.5 bottles) $10-12 1 Bottle $8+
Disadvantages Status Typically BIB wine is associated with low income consumers (usually college students) Bottled wine is more appealing than bagged Less Variety Typically brand names such as Vella and Franzia only have five-six types of wines available in BIB Quality Plastic is Transparent Subject to light degradation Plastic can alter flavor of product if over exposed
P.I.C.U.M Protection: spill-proof, shatter-proof, leakproof, durable, secondary packaging omits light degradation Information: variety of wine(standard of identity), directions for usage, brand, alcohol by volume (8%), history of brand
P.I.C.U.M Containment: adhesive heat seal, leak proof airtight tap, box protection bladder from puncture Utility of Use: AIRLESFLO tap, box for dispensing product, refrigerator friendly packaging Marketing: wine bottle equivalent depicted, California wine reference, colorful eye-catching
Environmental Implications Recycling Plastic products are recycled and remade more easily than glass into a variety of products Recycled glass products can be made into a slim arrangement of other products such as; vases, pitchers, other glasses, and countertops Large variety of remade recycled plastic products are available on the market today. These include; fibers made for clothes, plastic lumber, park equipment, furniture, bags, and many more
Questions 1. What is the primary and secondary packaging of BIB wine? 2. What type of plastics are used in the Airles flo tap? 3. True or False: Plastic emits more greenhouse gases than glass. 4. How long does BIB wine last opened? 5. Name two advantages of a wine bag vs. wine bottle.
Questions: 6. Are grape harvesting bins rigid, semi-rigid, or flexible? 7. True or False: Glass products create more recyclable products than plastic. 8. Name a disadvantage of plastic bag vs. a glass bottle. 9.True or False: The packaging AND product are aseptically processed 10. Name one other product that can be packaged in a polyethylene bladder bag.
