Polyéthylène téréphtalateIndex. décimale : 668.4 Plastiques, vinyles Résumé : For recycling to function successfully, the EU has defined five fields of action, among them: plastics. The reuse of plastics as often as possible is a common goal of politics, special interest groups, and business. But the opinions on specific measures are divided, as became clear at the conference of Petcore Europe, an association of the PET industry. Note de contenu : - Plastic packaging is under surveillance
- Technical trends in PET bottles and packaging
- Brand-Name compagnies: Self-commitment and lighthouse projects
- Recycling as a large organizational project
- FIGURES : 1. Probably the most widely publicized presentation of new plastics recycling. Its goals (1,2 and 3) are clear, but their realization has to be coordinated among many actors. The Ellen Mac-Arthur Initiative has an interesting approach - 2. Additional cumulative demand for PET type bottles in Europe between 2016 and 2020. Bottles for silent waters will increase strongly, while the demand for carbonated soft drinks will fall - 3. Design for recycling : P&G demonstrates it with a new detergent bottle.

Emballages en matières plastiques -- RecyclageIndex. décimale : 668.4 Plastiques, vinyles Résumé : The image of plastic packaging suffers due to one-sided negative reporting by the media. But from an ecological point of view, polymer packaging solutions offer many advantages when compared with other packing materials. Admittedly, suitable collection and recycling systems are the prerequisite for this. Note de contenu : - Good product protection saves CO2
- Lightweight material saves resources
- Collection and recycling systems as prerequisite
- FIGURES : 1. Optimized packaging can markedly reduce the amount of food thrown away relative to the quantity produced - 2. The weight advantage of plastic packaging becomes clear in direct comparison with other packing materials - 3. Based on a cup weight of 4,7g and 360 days/year, the result is a daily material saving of approw. 565 million yoghurt cups - 4.

Traîtements de surfaceIndex. décimale : 668.4 Plastiques, vinyles Résumé : The Calvasol method provides a flexible, economical, and efficient way to functionalize films with corresponding coatings. Compared to alternative methods, the applied layer thicknesses are in the range of 0.1 to 10 nm which reduces the consumption of chemicals and energy in processing. Note de contenu : - Avoiding high energy consumption for drying
- Treatment and coating in one process step
- Direct integration into the extrusion process
- Further development of functional chemistry
- FIGURES : 1. Schematic representation of the Calvasol method that combines the corona treatment and aerosol application. It is used for the permanent andi-adhesion, antifog or antistatic functionalization of films - 2. The aerosols are applied to the film from below. This has the benefit that the functional molecules can be anchored in a very thin and even layer - 3. The Calvasol system can be integrted directly into the lamination process with no negative influence on the lamination adhesive - 4. Measuring the contact angle of a film coated with and without Calvasol shows the influence of the Calvasol antifog function : The goal is to create a surface with maximum hydrophilic properties, indicated by a small contact angle in the measurement with water. The greater the contact angle (image on the right), the poorer the antifog effectEn ligne : https://drive.google.com/file/d/13hytvqc7_RbMNMMsWKL1MxA45wqXt11w/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28474

As early as 1974, Otto Graf GmbH started offering rainwater storage tanks. But even before that time, the company had been successful in container production, and still is today. A significant factor of success when implementing their solutions − some of which are demanding − is the development environment based on PTC Creo and supported by Inneo.
