-之材料組織耐滲透性測試（PUSH-OUT TEST）

耐滲透性測試涉及將探針（通常是針或圓錐形）插入材料中。對于薄的柔性材料，耐滲透性是重要的終使用性能參考，其中鋒利的產品會損壞包裝材料。各種參數會影響對滲透的響應，例如膜厚，機械性能，穿透速度，探頭尺寸和形狀。

A comparative biomechanical analysis of term fetal membranes in human and domestic speciesBorazjani A, Weed BC, Patnaik SS, Feugang JM, Christiansen D, Elder SH, Ryan PL and Liao JAmerican journal of obstetrics and gynecology, 204(4), 365. e325-365. e336. (2011)

OBJECTIVE: The purpose of this study was to biomechanically characterize and compare human, porcine, equine, and ovine fetal membranes.

STUDY DESIGN: Noncontact metrology was used for topographic analyses. Uniaxial tensile testing was performed to resolve specific biomechanical values. Puncture force and radial stresses were determined with biaxial puncture...Read More

ASTM D5748 - Standard Test Method for Protrusion Puncture Resistance of Stretch Wrap FilmASTM International, West Conshohocken, PA, 2012,

Significance and Use

Puncture resistance is very important in end-use performance of stretch wrap film used in consumer and industrial product applications. Puncture resistance is a measure of the energy-absorbing ability of a stretch wrap film in resisting a protrusion. The test method is designed to provide the user with a means of measuring the stretch wrap film's puncture...Read More

ASTM F1306 - Standard Test Method for Slow Rate Penetration Resistance of Flexible Barrier Films and LaminatesASTM International, West Conshohocken, PA, 2016,

Significance and Use

4.1 Penetration resistance is an important end-use performance of thin flexible materials where a sharp-edged product can destroy the integrity of a barrier wrap. This will permit package entry/exit of gases, odors, and unwanted contaminates, causing potential harm to the product and reducing shelf-life. Material response to penetration will vary with numerous...Read More
