Set your bottled water products apart from your competition.
Now you can create strong product differentiation for your bottled water operation by using bottles made from corn-derived plastics as the smart, environmentally friendly alternative to petroleum-based (PET) plastic bottles.
For more information about PLA, please visit NatureWorks.
The compostible bottles are produced by using preforms made of polylactide (PLA), a 100% corn-based plastic developed by NatureWorksLLC, a wholly-owned Cargill company, Minnetonka, Minnesota.
PLA bottles look exactly like traditional PET bottles. What you can do
with PET, you can do with PLA.
Plus, with Norland’s new Freedom™ PLA Series small bottle blow molders, you can make your own PLA bottles when you need them—and save. The Freedom Blow Molder may cut your bottle costs by 25% to 50%, depending on location, size and volume of your business.
Freedom Series PLA blow molders free you from the high costs of vendor-supplied pre-blown bottles. You’ll also be free to produce your own bottles when you need them. No more waiting for bottle deliveries that may not arrive in time. You’ll also free up valuable plant space from storing large quantities of empty bottles. Choose from three models that produce 1500, 3000 or 4500 PLA bottles per hour, respectively.
Norland also offers a PET version of the Freedom Series blow molders.
About PLA Bottles:
PLA bottles offer a significant advantage to producers of bottled water, juices, oils and other liquid products—they are environmentally friendly. While it is estimated that petroleum-based plastic products require thousands of years to decompose, PLA products are compostible within 45-90 days. This compost material can then be used to fertilize the next year’s crop of corn, completing the cycle of a totally renewable resource. PLA plastics contain no petroleum, and require 20-50% less fossil fuel to manufacture than PET plastics.
The steps for making PLA and PLA bottles:
- Harvested corn is broken down to isolate corn sugar (dextrose).
- The dextrose is processed into lactic acid.
- The lactic acid is then made into PLA pellets, which are used to make
preforms for bottles, as well as other types of packaging containers.
- PLA preforms enter Norland’s Freedom™ blow molder, heated to the
optimum temperature(70˚C), then stretched by air pressure into the desired shape and size.
- The new bottles exit the blow molder, cooling as they go.
- They are filled with water, fruit juice, or other liquid products, and sold to consumers
- The used bottles can then be composted* and used as fertilizer for growing more corn.
Norland’s Freedom Series blow molders can efficiently produce 1,500, 3,000 or 4,500 bottles per hour, depending on the model chosen. In addition to cutting bottle costs, other important benefits include providing bottling companies the capability to produce their own bottles on-site as needed, saving inventory storage space and eliminating delivery problems; and ability to handle a variety of bottle preform shapes and sizes to 50 oz (1.5 L). Easy-to-change molds make moving from one bottle size or shape to another quick and easy.

NOTE: Preforms made of PET and PLA have different characteristics. For PET, preforms must be preheated to 100˚C, while PLA preforms must be heated to just 75˚C. Using PLA preforms in a PET-calibrated blow molder will cause the PLA preforms to destruct.
