Abstract

With renewed interest in food packaging materials that can be both recyclable and compostable and the environmental concerns about plastic pollution in the terrestrial and aquatic ecosystems, molded fiber food packaging is experiencing an unprecedented demand around the globe. However, the phase-out of per- and polyfluoroalkyl substances (PFASs), commonly used as a water/grease resistant agent in food contact molded materials in many jurisdictions, has posed a significant challenge to the industry. This perspective outlines a recently developed solution to replace PFASs through the application of a layer of cellulose nanofibrils on the surface of molded fiber objects.

无PFAS(全氟和多氟烷基物质)模制纤维:未来已经到来。

随着人们对可回收和可堆肥的食品包装材料的重新兴趣，以及对陆地和水生生态系统中塑料污染的环境问题的关注，模塑纤维食品包装在全球范围内正经历着前所未有的需求。然而，在许多司法管辖区，全氟烷基和多氟烷基物质(PFASs)通常用作食品接触模塑材料中的抗水/抗脂剂，其逐步淘汰对该行业构成了重大挑战。这一观点概述了最近开发的一种解决方案，通过在模塑纤维物体表面应用一层纤维素纳米原纤维来取代全氟丙烷。

期刊介绍： Biointerphases emphasizes quantitative characterization of biomaterials and biological interfaces. As an interdisciplinary journal, a strong foundation of chemistry, physics, biology, engineering, theory, and/or modelling is incorporated into originated articles, reviews, and opinionated essays. In addition to regular submissions, the journal regularly features In Focus sections, targeted on specific topics and edited by experts in the field. Biointerphases is an international journal with excellence in scientific peer-review. Biointerphases is indexed in PubMed and the Science Citation Index (Clarivate Analytics). Accepted papers appear online immediately after proof processing and are uploaded to key citation sources daily. The journal is based on a mixed subscription and open-access model: Typically, authors can publish without any page charges but if the authors wish to publish open access, they can do so for a modest fee. Topics include: bio-surface modification nano-bio interface protein-surface interactions cell-surface interactions in vivo and in vitro systems biofilms / biofouling biosensors / biodiagnostics bio on a chip coatings interface spectroscopy biotribology / biorheology molecular recognition ambient diagnostic methods interface modelling adhesion phenomena.
