Tag: Slack fill

According to packaging experts, a significant portion of what appears to be empty space in many consumer products is caused by 'slack-fill,' which is a necessary part of the manufacturing and shipping process. This is why the question, "are protein powders supposed to be half full?" is a common concern for shoppers who feel they might be receiving less product than they paid for.

In the dietary supplement industry, class-action lawsuits addressing product claims are not uncommon, and Isopure, a prominent protein brand, has faced its share of public scrutiny over alleged deceptive practices.

According to packaging experts, powdered products like protein powder are typically filled with a certain amount of initial air space to allow for natural settling. This phenomenon is the primary reason why protein powder containers are only half full upon opening, and it's less about deceptive marketing and more about physics.

According to manufacturers, nearly all powdered supplements, including protein, are sold by weight, not volume. So, why is my protein powder half full when I break the seal? This common question stems from a phenomenon known as 'slack-fill,' which is a necessary part of the manufacturing, packaging, and shipping process, ensuring you receive the correct amount of product while maintaining its quality.

According to a 2017 study by CDA Appliances, the average bag of crisps is actually 72% empty. So, why are bags always half full, leaving many consumers feeling short-changed when they open their favorite snack? The answer is a fascinating combination of product protection, food science, and manufacturing efficiency.

In 2014, a class-action lawsuit was filed against Isopure's parent company over allegations of protein spiking. The Isopure controversy refers to this and other legal and consumer complaints that have since challenged the brand's product claims, including deceptive packaging and potential contaminants.
