Flexible food packs bulk up with superior performance

Rick Lingle in Flexible Packaging on July 31, 2018

A booth at the Powder & Bulk Solids show yielded a pair of breakthrough flexible packaging innovations, the Termalock Powder Bag and Flexible Bucket, applicable for food ingredients and more.


It’s not just people who bulk up, but packaging can too, as these two examples from a recent exhibition demonstrate while showing that bigger can be made better.

An April day began favorably at a suburban Chicago exhibition managed by Packaging Digest’s sister publication, Powder & Bulk Solids, when the first stop of the day at one booth yielded two “plus sized” flexible packaging innovations for food products.

The bait that drew my immediate attention was the “new” signage at the booth of Fres-co System USA. Inside and most prominent was a pallet-load display of the vendor’s new Termalock Powder Bag and, at a small kiosk a few feet away, the intriguingly named Flexible Bucket.

Handling the company's booth duties was Abby Possinger, market development manager, food and feed ingredients, who was enthused about the 2018 debut of a new bag and specialized design. Unlike multilayer kraft paper bags, the Termalock Powder Bag’s durable multilayer structure provides a barrier for sensitive bagged powders, especially food ingredients.

As notable is the valve’s specialized one-way channel design that prevents clogging associated with standard open-mouth bags with a one-way valve. Another benefit of the packaging is that when stacked and palletized, the air-tight bags make for stable pallets versus alternative formats, Possinger pointed out.

Additional information was provided in a follow-up interview for both of these packaging introductions to discuss key features, options and more starting with the Termalock bag, which took several years’ research and development to perfect.


What customer need does it address?

Possinger: The Termalock Powder Bag directly addresses recurring problems that plague the producers of bulk powders, namely oxidation, moisture and dehydration. The one-way degassing valve with built-in vent chamber offers 100% airtight protection and a near-zero moisture vapor transmission rate (MVTR). With flat storage when empty and perfect palletization when filled, the advantages over alternative packaging options are overwhelmingly apparent.


What is considered the industry standard format and why is this better?

Possinger: Traditional industrial packages have air holes that allow premium powders to oxidize, dehydrate, or come in contact with moisture during their transport from the producer to the end user. The Termalock Powder Bag is an open mouth, airtight package that forms stable pallet. It can package a wide range of products, including proteins, amino acids, vitamins, probiotics, premium sweeteners, chelating agents and among many others.

What are the key features?


Safe and Efficient Transport Designed with palletization in mind, weight distribution concerns will be dramatically minimized. Traditional Kraft-Poly packaging often forms an unstable, and unsafe “mushroom-like” profile when palletized.

Space Savings It would take 34 truckloads of fiber drums to ship the same product volume as one truckload of Termalock Powder Bags. And prior to filling, the bags store flat, saving space in a warehouse for more product.

Reduced Complaints and Returns Customers expect product to arrive in the condition it left the factory or warehouse. When powdered ingredients are sealed against moisture, dehydration, light, oxygen and rodent and insect infestation, degradation becomes a worry of the past.

Longer Shelf Life According to customers, our industry-leading sealing technology extends their products’ shelf lives by up to two years.

What basic structure and options do you offer?  

Possinger: The basic material structure of polyester/aluminum/nylon/polyethylene varies by product or customer need, but the durable high-barrier film structure is combined with a one-way valve and built-in vent chamber.

Size is determined for each specific product, but the general size is for products weighing approximately 50 lb/25kg.

Also, vibrant, multi-color printing is always available at Fres-co to call attention to the product or brand.


What product categories and types is it suitable for?

Possinger: The Termalock Powder Bag is suitable for powder products in a wide range of product categories, including food, feed, pharmaceutical and cosmetic ingredients.
