Is Plastic Packaging Safe?
Many people have concerns about plastic containers leaching toxic molecules into the
contents of a product’s package. When a consumer is making a product choice, they need to be assured that the containers and packaging are safe.
The food, health and wellness industries, as well as body care manufacturers are addressing consumer concerns by utilizing a complex and costly certification process to show that their product meets a higher standard. That it is what the label says it is, for example: organic, gluten free, not tested on animals, non-GMO, no hormones, dyes or pesticides, etc.
Producers need packaging solutions that safely protect the contents freshness, maintain shelf-life, be attractive, sustain shipping world-wide, and not add a hefty cost to the product. One of the most cost effective, non-reactive, and safe container is HDPE (High-Density-Polyethylene) plastic with the recycle #2 symbol, for manufacturers and for consumers.
What’s in plastic that can make it unhealthy?
Plastics are made from many chemicals, and some are potentially harmful. Some manufactured plastics leach plasticizers like phthalates(1,2) or bisphenol A (BPA) (3). If Phthalates or BPA is utilized, they can be released from the container relatively easily because their molecules are not bound with the plastic container (4). Studies reveal that phthalates and BPA appear to cause health issues, as they are hormone distrupters (5).
What makes HDPE safe for the US, EU, Britain, Canada, Australia & New Zealand?
HDPE (High-Density-Polyethylene) is the one of the safest and most widely used plastics on the market(6). HDPE is a thermoplastic made from petroleum products, specifically ethylene, that has a high strength-to-density ratio (7). This plastic is remarkably safe because it is very non-reactive and highly stable (8, 9). HDPE has excellent chemical resistance. It is acid resistant, alkali resistant, biocompatible, moderately biodegradable (10-12), BPA free(13), and phthalate free (13).
It is approved by the United States Food and Drug Administration (FDA) (14). It is also approved by the European Union Food Safety Authorities (15), The British Foods Standards Agency (16), The Food Standards Australia New Zealand (FSANZ) (17) and The Canadian Food Inspection Agency (18).
How is HDPE regulated?
Here in the States, the FDA continuously regulates HDPE, ensuring manufacturer safety standards are met and maintained. Since plastics can contain residual or unreacted quantities of monomers and process additives such as antioxidants (14), all plastics intended for food use must meet stringent FDA safety standards before they are marketed to consumers. This is done to ensure any potentially harmful substance levels are kept well below regulatory limits (14). HDPE’s versatility and inherent stability (strong acids or bases do not attack it) make it the most commonly manufactured and utilized packaging plastic, and it has no known "health-safety" issues (19).
What kind of HDPE packaging does Mineral Logic and AgTonik use?
HDPE doesn't leach any chemicals, so it is well-suited for making bottles for the storage of beverages and containers for food14. HDPE products include packaging like milk jugs, juice containers, food storage containers (keeping your nutrients organic), plastic bags, plastic films, and water pipes for domestic water supply (20). Mineral Logic™ and AgTonik™ utilize FDA Food Grade stainless steel vessels, mixers, blenders, milling equipment and trays for extracting and drying.
We also exclusively utilize a variety of plastic container packaging in assorted shapes and sizes, manufactured from FDA Food Grade HDPE. These containers safely store and maintain all our naturally low in pH, organic products like MLG-50. All HDPE containers are recyclable and have the #2 surrounded by chasing arrows embossed on the bottom of the container (21), which is the HDPE resin identification code. Almost all curbside recycling programs accept #2 HPDE, and recycled HDPE has proven as versatile as virgin HDPE. Polymers used to make plastic Food Grade Containers like HDPE pass all FDA standards.(14) You can be assured that it’s the best plastic on the market and a healthy choice for fulvic product packaging.
