Packaging company sees steady growth in demand for new sustainable line

As consumers are becoming more environmentally conscious, the demand for sustainable packaging options continues to increase every year. In response to this demand, as well as to reflect their own sustainability values, Warren Packaging has been working on developing a sustainable packaging line. “We have been working on this line for a couple of years,” says Mike Dittenber of Warren Packaging. “We trialed a lot of different designs and ideas, and these turned out to be the most efficient and popular version of the packaging,” he explains.


Customizable, recyclable and biodegradable
The new packaging is made out of paperboard, which is 100% recyclable and biodegradable, with a window made out of cellulose. “The window is very important,” Dittenber shares. “Right from the start of our research we found that visibility is something that consumers really look for. They want to be able to see inside the packaging and make sure that the product looks good. One of our partners came out with this cellulose window material, which is plastic free and biodegradable, and we decided to incorporate that as a window in our design. This really gives us the best of both worlds: visibility and sustainability,” he adds.

Besides the sustainability factor, there is another big positive to the paperboard packaging. Dittenber explains: “Any graphics that the customer wants can be added to the paperboard, and the graphics can cover the entire packaging. The graphics can be used for marketing purposes but also for educational purposes – explaining to the customer how this packaging helps them support the environment, for example. The fact that we can print directly onto the paperboard also means that the customer is using less materials and has less steps in the process, because they don’t have to apply additional materials as they usually do with standard plastic clamshells.”

Flexibility in design
The design of packaging is very versatile, and Warren Packaging is able to fully resize the design to make it fit any product. “We currently have this packaging on retail shelves in a few different styles: a 16 oz grape tomato clamshell, a 1-pound clamshell for tomatoes on the vine as well as a design for onions. Those are the designs that are currently being produced, but we have several other options available for different products as well, so the growers and packers are able to visualize what the end-product will look like – but we can also fully customize and resize it to fit the specific needs of a customer,” Dittenber shares. Warren Packaging is also running the master cases to fit the clamshells into, to be able to provide their customers with a full package deal.

In addition to working with the customer to find the perfect design for their product, Warren Packaging also works with the customer to find the perfect design to fit into their packaging line. “We take care of the design and manufacturing of the packaging and then we send it off to the customer and they pack their products with them. We work with the customer to find the best style to fit into their existing set-up,” says Dittenber.


Demand expands steadily
After finding the perfect design for their sustainable packaging line, Warren Packaging has seen that the demand for the new lineup has been steadily growing since the launch. “When the pandemic hit, we were happy that we decided to go with this closed-concept packaging, rather than some of the open-concept styles we had initially trialed. When the pandemic hit and consumers started to worry about safety in stores, our packaging continued to see steady growth in demand because they offer the same sense of security as the plastic clamshells,” Dittenber says.


For customers who aren’t ready to commit to fully changing their packaging, Warren Packaging also has a sustainable wash-away label available. This option allows customers to make their plastic clamshells more sustainable. “We developed this label with our material supplier for packers and growers still utilizing plastic clamshells. The wash-away label is designed so the consumers can remove the label from the clamshell before recycling so the clamshell can be recycled correctly without the label/adhesive,” Dittenber explains.

“We are seeing a lot of interest and really gaining traction on our sustainable options. It’s the future of clamshells – to transition to more sustainable options and eventually from plastic into paper – and we are happy to be able to offer it to our customers,” he concludes.

Japanese tomato harvest robot in action in Tomatoworld

A new tomato harvesting robot has recently been driving through the paths of Tomatoworld. It is the latest product of inaho Europe, a subsidiary of the Japanese company inaho.  “The purpose of launching the demonstration at Tomatoworld is to allow more interested people to see the robot in operation,” says Takahito Shimizo, managing director of inaho Europe. “We want to demonstrate the robot and receive more feedback from growers, in order to develop and increase the value of the robot.”

Snack tomato robot
Tomatoworld is a horticultural information and education center in Westland, Netherlands. In the greenhouse, snack tomatoes are grown.

Takahito Shimizo shows how the robot is a fully automatic harvesting device for snack tomatoes. “The AI algorithm identifies the ripe fruits by color and size and then harvests the ripe snack tomatoes.”

inaho has already conducted field trials with growers in Japan and demonstrated a reduction in human working hours of around 16% by setting up a workflow in which robots harvest during the nighttime before humans do.

Meanwhile, inaho also found that there are differences between Japanese and Dutch growers in terms of harvest and post-harvest operations. “For example, the standards for the picking appropriate color of the fruits and the frequency of harvesting are different,” says Takahito.

In order to develop a solution that is more suitable for Dutch growers, inaho is keen to get a better understanding of the Dutch growers’ practices and receive more operational feedback from them. In this context, inaho is also actively seeking a grower partner who would be able to carry out a field trial of the harvesting robot.

Growers welcome
The demonstration in Tomatoworld also contributes to this: growers are invited to come and see and assess the robot. “We are happy to discuss details about the robot, such as its functions and expected future updates. We can also provide simulations to calculate the labor and cost savings, based on the results of the trials in Japan,” Takahito says.

It is not the Japanese company’s first robot. inaho already launched an AI-equipped asparagus harvesting robot (video) in 2019. They are also working on a robot that can phenotype plants. inaho operates according to the Robot-as-a-Service (RaaS) business model – paying per harvested product.

BelOrta launches 100% recycled & recyclable strawberry punnet

Starting this week, the first Belgian strawberries from BelOrta will be packed in new packaging. These are Tray2Tray punnets made from recycled raw materials that are still 100% recyclable. Consumers can recognize these punnets by a special logo.

Starting this week, the first Belgian strawberries from BelOrta will be packed in new packaging. These are Tray2Tray punnets made from recycled raw materials that are still 100% recyclable. Consumers can recognize these punnets by a special logo.
BelOrta launches 100% recycled & recyclable strawberry punnet 105

Together with Fost Plus and Infia, BelOrta says it is taking ‘the next step in increasingly sustainable production and distribution’. “This step contributes to a circular economy. Not unimportant, because recent figures show that we are eating more and more home-grown strawberries,” according to the cooperative. 

Closed cycle

With the strawberry punnets, no empty strawberry tray has to end up on the waste mountain from now on, because every packaging can be processed and reused as raw material for new packaging.

Jo Lambrecht, Sales & Marketing Manager at BelOrta: “With this Tray2Tray concept, in which new punnets are made from used packaging, we contribute to a circular economy. We have been working with so-called ‘r-PET’ as a raw material for 4 years, recycled from water and soft drinks bottles and other PET packaging that consumers collect. The New Blue Bag has recently been introduced to us for the collection of all plastic packaging waste. 

By the way, Belgians are champions in sorting and collecting waste, which makes a difference to a healthier and more pleasant living environment. Thanks to new techniques, developed under the impulse of Fost Plus, we can now also sort these r-PET punnets (cf. the new blue bag) and recycle them into flakes, after which they are used again as raw material for the production of new packaging, such as for our strawberries and berries. This completes the cycle.”

450 tons less CO2 emissions per year

But what about ‘the most sustainable packaging is no packaging’? Lambrecht: “That is indeed true for many products, often including food. We try to avoid or reduce the use of packaging wherever possible. But for sensitive and perishable products, well-chosen packaging is crucial in the fight against food waste. Various tests, including with strawberries and berries, have taught us that well thought-out packaging makes all the difference. Wasting less food reduces our ecological footprint. Moreover, r-PET as a raw material has a low ecological footprint compared to many other materials.”

For BelOrta, the replacement of PET by r-PET means a reduction of 450 tons of CO2 emissions per year. 

Belgians eat an average of 1.94 kg of strawberries per year

More than 9,000 tons of strawberries were sold in 2020 via BelOrta. With over 100 different growers, the acreage of strawberries at BelOrta is about 300 hectares, an increase of 4% compared to the previous year.

Recent figures from market research agency GfK also show that the average Belgian ate 1.94 kg of strawberries in 2020. That is a growth of more than 12% compared to the previous year. Elsanta, Portola, Elegance, Malling Centenary, Sonata and Sonsation are the main varieties at BelOrta.

Sustainable packaging company adds cardboard tray to its portfolio

Cascades, a North America and European based packaging company, is launching the first thermoformed cardboard tray. The product is made from 100 percent recycled and recyclable cardboard and has a recyclable water-based barrier coating which prevents moisture. “The cardboard tray makes a true alternative to plastic and foam trays,” says Jacques Bissonnette with Cascades’ Canada office. “Sustainable packaging is getting more important, enforced by retail regulations as well as consumer demand,” he added.

“In November of last year, we did a successful soft launch in Canada with the cardboard tray for mini cucumber. Just this month, a US customer started using the trays for sweet corn.” The product is available in a range of different sizes from 8 2/16 inches length, 8 11/16 inches wide to 1 11/16 inches height. However, Cascades also offers tailormade solutions. The tray is suitable for a wide range of fruits and vegetables, from Brussels sprouts to bell peppers, green beans, and much more. “The package will stand out even more if it is combined with a compostable top seal film, making it a fully sustainable solution,” Bissonnette added.

Telling the story
“We think it’s really important to tell the story how sustainable packaging can help to reduce the environmental footprint and achieve the retailer’s sustainability goals.” To support the story, Cascades has developed an LCA (Life Cycle Assessment) for all its product lines.

“This means we can tell the client exactly the amount of environmental footprint reduction they will be able to achieve with one of our sustainable solutions compared to the material they are using currently.” A lot of the current plastic packaging as well as foam packaging can be replaced by this cardboard solution and has proven to offer equivalent shelf life to plastic”. The new cardboard tray works with existing machinery and tooling for plastic trays, meaning that no extra investment is required for producers or packers looking to make the switch to cardboard.”

Cascades also invested in research on the consumer side. “It’s not only the demand for sustainability that has grown but also the willingness among consumers to put their money where their mouth is,” said Bissonnette. Most consumers are willing to pay a bit more for produce that is sustainably packaged. Also, better labeling on the packaging would encourage consumers to buy more green, sustainable packaging. “It is still a bit more expensive but both producers and retailers should not be afraid to raise their prices a bit. We are not talking about full dollars but just a few cents, ” Bissonnette noted.
