ASTM D1709-03
ASTM D1709-03 is a procedure that requires the use of a free-falling dart to measure the impact resistance of plastic film. It measures a film's resistance to breakage caused by the impact from a weighted dart dropped from a given height. There are numerous packaging applications where packaging films are subject to handling, transport, stacking, and inadvertent impact. ASTM D1709-03 outlines a standardized method to measure the amount of energy needed to make a flexible plastic material fail and is helpful for manufacturers to measure the toughness and durability of the material. The standard contains proven testing methods that produce consistently reproducible data to be used for quality control.ASTM D1709-03
Significance
Test ASTM D1709-03 is an important test methodology that is employed in package and plastics applications where impact resistance is important to the product and package. Products can get damaged and more costly due to breakage or puncture of the film during delivery when high on impact. Dart drop impact resistance testing can be used to compare the resistance of various formulations of material, check the processes used in production, and decide the suitability of a film for the required use. The test also supports quality control programs by identifying variations in film performance before products reach the market. By testing materials consistently following ASTM D1709-03, manufacturers can provide packaging materials that are more likely to withstand real handling conditions. Scope ASTM D1709-03 is the method for measuring the impact resistance of plastic film by means of a free-falling dart in a controlled test. The standard specifies procedures for measuring the weight required to cause film failure and assessing material toughness. It applies to plastic film manufacturers, packaging companies, testing laboratories, material suppliers, and quality assurance teams involved in film development and performance evaluation.
