Innovia Films Launches Hot-melt PSA Film for Freezer Label Applications:

-
Image
Innovia Films launches a uniquely engineered two-sided coated cavitated film for pressure sensitive labeling (PSL) applications which is marketed as Rayoface™ AQBHA. The polypropylene (PP) film offers outstanding printability with a backside coating specifically designed for hot melt pressure-sensitive label coating. HMA with Anti-migration Properties: The film is 58 microns thick, has a printable top-coating, and an adhesive receptive coated surface on the reverse side that provides anti-curl and migration properties with hot melt adhesives. Rayoface™ AQBHA offers good moisture resistance and cold temperature performance, making this the perfect material for fridge and freezer applications. “As more SKU’s move to polypropylene containers, having a label made from the same material supports the design for recycling criteria for filmic facestocks”, explains Lucija Kralj, business unit director labels EMEA. Rayoface™ AQBHA has undertaken extensive hot melt barrier testing and the film re

Today's KNOWLEDGE Share:Avocadro Fibers

Today's KNOWLEDGE Share Researchers Use Fibers from Avocado Trees as Reinforcing Material in Packaging A study published by the University of Cordoba, in which the University of Girona also participated, has found a way to manufacture a prototype of a material for food packaging that is more ecofriendly. The study manages to produce a prototype of a more durable material that increases the biodegradability of food packaging. It partially replaces its bioplastic with cellulose fibers extracted from the branches and leaves of the avocado tree. Replacing a Portion of the Bioplastic Used in Food Packaging: It exploits waste devoid of any added value until now: residues from the pruning of the avocado tree; Spain is the main producer of avocados at the European level, with production being concentrated in the Axarquia region of Málaga. Although plastic allows food to be packaged safely and hygienically, its extensive use constitutes a significant environmental challenge due to its limit

Today's KNOWLEDGE Share :Microrobots in bacteria pollution

Today's KNOWLEDGE Share Microrobotic Swarms Tackle Microplastics and Bacteria Pollution In a recent study published in the journal ACS Nano, researchers reported how swarms of microscale robots, or microrobots, collected microorganisms and plastic fragments from water. The bots were then cleaned and put to use again. Cleaning up outdated food packaging, abandoned kid's toys, and other poorly managed plastic garbage from rivers and oceans becomes harder when it degrades into microplastics. These microscopic pieces of plastic also draw bacteria, even pathogenic ones. The minute size of microplastics, measuring 5 millimeters or less, introduces an additional layer to the plastic pollution issue. Animals can ingest these particles, posing potential harm and leading to their incorporation into the food chain, ultimately impacting humans. While the complete health implications for humans remain unclear, it is important to note that microplastics themselves are not the sole focus of c

SABIC Introduces High-performance Injection Molding PBT for Medical Applications

-
Image
SABIC announced the availability of VALOX™ HX325HP resin. It is a new high-performance, medical-grade, injection molding polybutylene terephthalate (PBT) resin. This resin is developed especially for high-precision parts, such as components of insulin delivery pens, insulin pumps, auto-injectors and continuous glucose monitors. It combines outstanding processability with high chemical resistance and validated biocompatibility. SABIC featured VALOX™ HX325HP resin at NPE2024. Complies to International Biocompatibility Standards: The new medical-grade PBT resin has passed stringent injection molding trials. It demonstrated high flow even in complex designs. It has excellent mold release properties with lower shrinkage variation compared with competitive engineering plastics. In service, VALOX™ HX325HP resin delivers high resistance to a wide range of chemicals for the mitigation of environmental stress cracking (ESC). It offers compatibility with ethylene oxide (EtO), gamma irradiation an

Shindo releases innovative one-part and low viscosity matrix resins for composites

-
Image
Shimteq™ RSN ACS01 is a very low viscosity resin that exhibits 50 mPa-s at 25℃ and can be stored at room temperature. As a one-part curable type, it is a thermosetting resin that undergoes a curing reaction when heated as it is. Commercially available two-part thermosetting resins such as epoxy resins and unsaturated polyesters are normally used by adding hardening agents and other additives to the main resin before mixing. Shimteq™ RSN ACS01, however, is a one-part curable type, eliminating the need for mixing process and allowing storage at room temperature, contributing to simplified material storage management in the manufacturing process and stable quality of cured products. In addition, the use of low molecular weight liquid monomers and oligomers allows for low viscosity for use in RTM and infusion moulding methods. Even when composites with high fibre volume content, which are difficult to impregnate with resin, can be easily impregnated in both the in-plane and out-of-plane di

Today's KNOWLEDGE Share : Frozen Layer Thickness

-
Image
Today's KNOWLEDGE Share I recently heard of a customer observing huge differences in pressure to fill from two PP batches with checked identical viscosity data from capillary tests. When molding thin parts, the pressure drop becomes overwhelmingly dominated by the actual "frozen skin" thickness that develops rapidly during filling. With a thickness in the 100's of microns range the effective available thickness for flow will dramatically decrease in the case of thin parts. The pressure drop in a plate scales essentially with one over the cube of the thickness, so a tiny difference in the frozen layer makes a huge difference in pressure to fill ! In PP we see a very strong effect of nucleation, both induced by additives/pigments or due to flow ( Flow Induced nucleation). The tremendous amount of shear in the outer layers of the flow in Injection Molding will lead to a frozen layer thickness that varies a lot with molecular architecture (Mw in particular). This could be

Today's KNOWLEDGE Share Chemovator, the business incubator and early-stage investor of BASF, has successfully finalized an investment in Heartland. The Detroit-based startup is a frontrunner in the production of natural fiber plastic additives, and the latest addition to Chemovator's external-facing Elevate program. Heartland helps manufacturers to reduce the product carbon footprint of plastic and rubber products. Able to Reduce Carbon Footprint on an Industrial Scale Supported by a team of scientists, engineers, and technologists, Heartland has developed hemp-based materials that can be used as additives within plastic compounds. This breakthrough advancement in the world of sustainable material innovation improves properties with regard to flammability, bonding, dispersion, and bulk density, which are historically associated with processing natural fibers. As a result, natural fibers are now a viable market opportunity to reduce scope 3 carbon emissions in numerous industrie
