Applications & Processes
BiologiQ’s ESR resin is designed to be used with other thermoplastic resins on standard plastics process equipment. Processing is generally in line with existing processes but may require minor adjustments to process conditions, such as to processing temperatures.
BIOBLENDs® are made by blending BiologiQ’s ESR resin with other conventional fossil-fuel based resins. BIOBLENDs® normally start as Masterbatch pellets containing 50% ESR and 50% fossil-fuel resin which are blended on standard compounding equipment. Masterbatch BIOBLENDs® are then further down blended at the final process to obtain the desired ESR content. Example: for typical film applications, the BIOBLEND® Masterbatch that contains 50% ESR and 50% virgin LLDPE resin would be fed into the blown film hopper along with an additional 50% LLDPE base resin so that the final BIOBLEND content in the finished film would be 25% ESR and 75% LLDPE. Other ratios are also possible and can be easily established by the appropriate down blending configuration.
BiologiQ can provide BIOBLEND® compounded resins directly from our factory in Idaho for trial and production activities. Please contact the factory for a direct discussion of your specific needs.
ESR is a perfect resin for many blown film applications, including, for example, produce bags, agricultural film and industrial packaging film.
Blown films containing ESR can be processed on standard film blowing equipment. Films containing ESR have been successfully made with various grades of LDPE, LLDPE, HDPE, PBAT, PLA, PHA and others. ESR/LLDPE films as thin as 2.54 microns (0.1 mil) have been successfully blown. ESR generally adds to the bubble stability and to the increased strength of blown films.
For best results, we like to start with a 50% ESR BIOBLEND® Masterbatch to make film. The masterbatch should be let down with additional resin so that the final ratio of ESR is between 15% and 40% ESR in a mono-layer film or in any particular layer of a multilayer film. We have developed the following Film Processing Guide for reference when performing initial product trials.
Blow Molded Bottles containing an ESR BIOBLEND® can be made for health and beauty products (such as lotion bottles). ESR is a perfect material to enhance the sustainability of blow molded bottles containing HDPE or PP. You can achieve a reduction in fossil-fuel content without sacrificing performance.
SHEET EXTRUSION and THERMOFORMING
Polypropylene and Polystyrene are common materials for making thermoformed products such as cups, lids and electronic component packaging. Implementing an ESR BIOBLEND® solution adds sustainability to these products without sacrificing appearance or performance.
ESR Masterbatch BIOBLENDS® can be used on standard injection molding equipment to make a wide variety of products such as cups, cutlery, custom-designed plastic parts. Implementing an ESR BIOBLEND® solution adds sustainability to these products without sacrificing appearance or performance.
In addition to these standard processes, BiologiQ will work with you to make ESR based products available on your proprietary processes.
BiologiQ is happy to assist you with the optimization of processing conditions that may be necessary during your trial and production ramp up activities. Please contact us for further information.
