PLA Polylactic Acid

Lactic acid is produced by the breakdown of sugars by the lactic acid fermentation.

Lactic acid is also used for the acidification and preservation of foods (e.g., for sour cream and sauerkraut).

PLA is the bioplastics most commonly used in thermoforming so far.

PLA is well-known for its packaging for dairy products from Danone.

(NEW 2017: Crystallizable grades with a continuous service temperature of 120 ° C are being developed)

Properties of PLA

originally very brittle.  Density 1.21 to 1.43 g/cm 3   high transparency,

low processing shrinkage   Strong block inclination (Antiblock additives or silicone coating required)   Low migration values à Food packaging.

Continuous service temperature range - 20 ° C to approx. 60 ° C  (mixtures up to 68 ° C).

Thermoforming of PLA

According to blend, or after impact, a continuous unwinding with a large RADIUS is required. The most PLA films can be operated without preheating.

Forming temperature: air forming 80 to 100 °C

Vacuum forming approximately 90 to 110 ° C

Since the forming temperature range is relatively small, care must be taken on a uniform heating pattern.

Special machine options are not necessary

Tool technology: as for polystyrene processing.

Molding shrinkage: 0.2 to 0.5.
