The new standard for cheese interleavers: Monomaterial Paperlike

In the packaging world, the pressure to transition into more sustainable and recyclable materials has become a demand in the market, driven by regulations and a growing consciousness in consumers alike. This conversation is often defined in smaller decisions within the packaging world: pieces that are not always visible at first, but have a direct impact on the consumer’s experience with the product.

In the dairy market, cheese interleavers are a key decision-maker. It seems like a small detail, but it is essential for final quality, factory’s operational efficiency, and brand recognition when the consumer opens a packaging and takes out each slice.

The cheese interleaver: a small piece that impacts quality, food safety, and operations

The interleavers (sheets in between portions or deli cuts) serve several purposes at the same time:

• Allow for a consistent separation between portions during its consumption and during industrial processes
• Allow to preserve the presentation and quality of the product 
• Reduce friction in line when they need to be bagged, piled on top of each other, portioned out, or sliced

When this component is missing, there are common complaints: stuck slicers, breakage, shape loss, uncomfortable manipulation, “green” cheese, or premature decay because of storage conditions.

What makes Paperlike in cheese interleavers different from the rest?

Paperlike was born from a family of solutions that is looking for something very concrete: being sustainable and practical at the same time, without forcing industry to change everything.

In interleavers, Paperlike is translated as a coextruded foamed film with the adequate properties to separate individual portions (cheeses, bread, buns, and more), it is available in roll stock or individual units. This sheet behaves similarly to paper.

This is where its strongest and easiest to understand feature lies:

“It rips apart like paper, but it is actually a polyethylene film”

This means that, besides the management of this type of paper, it is a solution that fits within recyclability and circularity schemes when designed and managed correctly.

Key benefits of the Paperlike cheese interleavers

1) Protecting the product and support of lifespan

Besides separating, they also protect. In cheese applications, Paperlike was tested as a response to a real challenge by an allied producer: they were looking for an interleaver that maintained product quality and improved the performance. The result was a monomaterial interleaver that protected the cheese, supported its lifespan and helped reduce the risk of mold and bacteria growth in everyday use.

2) Fluid operation without skyrocketing investments

One of the most common learning outcomes from the food industry is that many sustainable alternatives are not adopted because of the high cost of switching technology such as machines, processing adjustments, and stopping production lines.

The operational promise of Paperlike is exactly the opposite of that: having solutions working in the existing machinery and facilitating a “one to one” solution, reducing barriers to adoption.

3) Recyclability by design: monomateriality as an advantage

In regulatory contexts and environmental goals, the conversation is moving towards materials with clearer routes to recovery. Paperlike, made out of polyethylene, is meant to facilitate circularity strategies and be compatible with recycling supply chains when being implemented with an integral focus.

4) Presentation and experience: rigidity, cleanliness, and order when being opened

The interleaver is also an experience. A good interleaver:

• Feels firm to the touch
  
• Is easier to manipulate
  
• Reduces frustration when being served or when separating portions
  

This detail, though small, translates into a perception of higher quality.

“A green cheese showed us the way”

Paperlike’s use as an interleaver was not a coincidence. The project had already explored food packaging applications, but our cheese packaging client was the one that pushed us to test the material in its most light weight version, and prove that sometimes innovation starts with the least perceivable component: the sheet that no one sees on shelf, but everyone feels when they open a package.

This trial opened doors to scale the Paperlike family towards other markets and needs (always with the same philosophy: practical solutions, accessible, and scalable)

Can you print a cheese interleaver? With Paperlike you can

This changes the rules of the game, because it becomes a functional element in a communication channel:

• Messaging regarding freshness/quality by the portion
• Information about the origin, traceability, or sustainability
• Clear instructions for end of life and recycling
  
• Emotional branding that goes along the package until it reaches the kitchen

In competitive markets, these contacts build trust and differentiate a product at the point of sale.

Let’s talk about your product

If you’re looking for cheese interleavers that protect your product, improve the performance in line, and help you move forward in your sustainability goals without unnecessary friction, Paperlike is a conversation worth having.
