Patent application: Returnable cold chain packaging composite

Ben Welter - Thursday, June 15, 2017

U.S. patent application 20170158411 (applicant Proprietect LP, Toronto, Canada):

"Provided is a reusable composite container comprising a thermally insulating inner container fitted within a durable outer container. The outer container can also be thermally insulating. In preferred embodiments, the inner container comprises expanded polystyrene and the outer container comprises one or more of expanded polypropylene (EPP), EPS (Polystyrene), EPE (Polyethylene), PEPP (porous EPP) and PS/PE (Polystyrene/Polyethylene). The composite container can be used to ship temperature-sensitive payloads such as perishable goods. To ship a payload (e.g., perishable goods) using a composite container 10 with a separable inner container 30 and outer container 20, the payload is first placed inside of the inner container 30 along with cooling means (e.g., ice pack, crushed ice, dry ice, PCM (phase change material), etc.)."

Outlast Europe's Martin Bentz spoke with T.EVO magazine this month about the company's new Xelerate fabric. The fabric, introduced at a German trade fair earlier this year, incorporates "heat spreader" technology, a process traditionally known for cooling electronic devices. Xelerate fabric features improved thermal conductivity, Bentz said, and is suitable for home textiles, sportswear and protective gear. In an email exchange with Phase Change Matters, Bentz declined to discuss specific partners or customers.

Warmilu, maker of the IncuBlanket infant warmer, reports that is on track for $300,000 in total 2017 sales after signing two distributors for Latin America, Africa and Southeast Asia: Relief for Africa Foundation and Maternova.

Thanks to PCM insert, luxury chocolates melt in your mouth, not in the box

Ben Welter - Monday, February 20, 2017

In hot climates, chocolates bought at retail shops can end up melting on the way home. Pluss Advanced Technologies of India has introduced a packaging insert to keep the sweets in solid form during transit.

Pluss PCM insertDeveloped for ITC’s Fabelle line of premium chocolates, the insert features inorganic phase change material contained in a non-woven film. Vishnu Sasidharan, vice president of new product initiatives at Pluss, says the PCM was customized to keep the chocolate between 3º and 9º Celsius. The insert, designed for one-time use, measures about 170mm x 70mm. The goal is to maintain product quality and texture for one to two hours.

“The product was launched about five months back,” Sasidharan says. “It was available only in one hotel chain within ITC group of hotels. The boutique has gained much traction only in the last few months with ITC expanding it to not only within their group but in all the 5 star/7 star hotels across India.”

Pluss is working with other chocolate/confectionary companies to offer similar solutions for premium temperature-sensitive products.

Sonoco ThermoSafe launches certification program for cold chain packaging pros

Ben Welter - Thursday, August 04, 2016

Sonoco ThermoSafe has launched the industry’s first academic offering to train and certify cold chain packaging professionals. The certification program was developed by Sonoco ThermoSafe’s ISC Labs in partnership with the Packaging School; Dr. R. Andrew Hurley, assistant professor of packaging science at Clemson University; and an advisory panel of industry experts.

Cold Chain training illustrationTwo levels of certification courses are available:

• The Fundamentals Course ($295), accessible now, is a self-paced online course that takes a systematic approach to developing a basic understanding of temperature-assurance packaging. 

• The Professional Course ($999; bio-pharma manufacturers get a $100 discount) is a one-day session conducted by university professors, lab engineers and industry experts. The live course provides hands-on instruction and interactive activities. It will make its debut Sept. 26 at the Cold Chain GDP & Temperature Management Logistics Global Forum in Boston.

“The TAP program shares decades worth of ISCLabs’ collective knowledge and expertise in design, development and qualification of temperature controlled packaging,” said Vishal Khushalani, director of global marketing and business development at Sonoco ThermoSafe. “The course goes further to cover topics including temperature monitoring, global regulations and distribution considerations of temperature sensitive products."
