”ILLIG热成型课堂培训“

ILLIG HQ Training Department Manager Mr. Jorg Schuster

ILLIG HQ Director Packaging Technology & Product Division Manager Mr. Sven Engelmann

 

      “第一期热成型技能培训班”从11月13日开始进入为期8天ILLIG培训课程中的第一部分-课堂培训,课程系由ILLIG HQ总部负责全球培训工作的Mr. Jorg Schuster、与技术研发的Mr. Sven Engelmann两位负责进行,ILLIG CHINA公司将其在海宁科技绿洲城全新装修完成的培训课堂与设施,提供给热成型培训班学员进行上课;培训课程在ILLIG总经理Dr. Heinrich Sielemann以预录的欢迎第一期热成型技能培训班学员到ILLIG CHINA公司上课的致词中展开,课程中Mr. Schuster以PPT与Video为学员们讲述ILLIG的热成型设备与设计技术,同时以与学员问答的方式进行讨论,课程进行热烈紧凑,接下来的几天课程将深入到热成型制程中材料、加热、成型、模具...等各项实际操作与技术相关主题,且在课题培训最后一天,Mr. Sven Engelmann为学员们准备了60题的热成型知识技能测验,以全面的检视协助学员的学习,他同时也已经为测验成绩第一的学员准备了奖品,让我们一起期待丰富的培训成果。

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.
