Choosing the best bottle for your filling line.

In liquid packaging , selecting the right type of bottle for your filling line can impact everything; from sustainability to product quality, to operational efficiency.

Two of the most common bottle types used today are PET (polyethylene terephthalate) and rPET (recycled PET). In an article from bottld.org it is estimated that the UK uses  38.5 million of these bottles every day.

From a regulatory standpoint in the UK, rPET containers with at least 30% recycled content are exempt from the Plastic Packaging Tax. This  makes them a cost-effective and compliant choice for manufacturers. In contrast, PET bottles without sufficient recycled content are subject to the tax, increasing operational costs. As Extended Producer Responsibility (EPR) regulations come into force, brands using rPET can also benefit from a lower environmental footprint and potentially reduced EPR fees. As a result, many companies feet that choosing rPET not only supports sustainability goals but also offers strategic financial and regulatory advantages.

While PET and rPET containers may look identical at a glance, they carry key differences that can affect your entire production process.

Here’s a breakdown of the core differences between PET and rPET bottles, and what you need to consider before choosing one for your filling line.

PET Water Bottles

When it come to choosing between PET and rPET for your filling line, here are some key factors to consider:

Product Compatibility

• Some beverages (like carbonated drinks) require bottles with higher pressure resistance.
• Ensure that rPET bottles meet the structural and barrier requirements of your product.

Filling Temperature

• Hot-fill processes require bottles that can withstand higher temperatures. Not all rPET bottles are rated for this.
• Confirm with your supplier if the rPET you’re considering is heat-stable.

Clarity and Branding

• If crystal-clear packaging is crucial to your brand identity, note that rPET may have a slight tint.
• Consider how this might impact shelf appeal or consumer perception.

Sustainability Goals

• Many companies are moving toward circular economy models.
• Materials that  help meet corporate sustainability targets and may be favoured by eco-conscious consumers.

Cost and Supply Chain

• Virgin PET prices fluctuate with oil markets, while rPET costs depend on recycling infrastructure and availability.
• Availability of rPET may be limited in some regions, affecting your production continuity.

Machinery Compatibility

• Ensure bottle dimensions and wall thickness match your existing filling and capping lines.
• Test both PET and rPET on pilot runs to check for variances in performance (e.g., in sealing, labelling, and filling speeds).

Regulatory Compliance

• For food and beverage applications, rPET must comply with FDA (U.S.) or EFSA (Europe) regulations.
• Ask suppliers for documentation and certifications.

While PET may offer consistent performance and clarity, rPET aligns more closely with sustainability trends and regulatory pressures toward circular packaging.

Before making a switch, karmelle suggest you audit your product needs, evaluate your machinery, and consult your packaging suppliers. A small difference in material can have a big impact on your brand image, environmental footprint, and production efficiency.

Why is Stainless Steel Ideal for Food Grade Filling Machines?

At Karmelle we often talk about the types of Stainless Steel we intend to use for a job. But why is stainless steel such a key resource for us and our filling machines?

In this post we explore what makes stainless steel the undisputed champion of food-grade machinery, and why Karmelle won’t use anything less.

Food production environments are tough on equipment. Exposure to moisture, heat, and a wide range of ingredients (some acidic, some alkaline) means corrosion is a constant threat. Stainless steel offers exceptional corrosion resistance, helping machines maintain their performance and structural integrity over time.

Why does that matter? Because corrosion can lead to contamination, and in the food industry, this can lead to violation of legislations such as The Food Safety Act 1990 and The Contaminants in Food (England) regulations 2013.

Stainless steel is a non-porous material, meaning it resists bacterial build-up and is easy to sanitise. Its smooth surface makes it simple to clean as a result it meets (and often exceeds) the hygiene standards set by global food safety regulators.

At Karmelle, we can design our filling machines to be both highly effective and hygienic, helping customers meet stringent industry requirements with confidence.

Food production is demanding. Machines are expected to operate around the clock, often under intense conditions. Stainless steel is incredibly durable and resilient, offering a long service life with reduced maintenance needs. For our customers, that means less downtime, lower costs, and more efficient operations.

At Karmelle, quality is non-negotiable. We don’t just meet industry standards; we aim to exceed them. That’s why we source only the best stainless steel, ensuring our machines are built to deliver optimal performance while maintaining product integrity. But our commitment doesn’t stop at performance. Stainless steel is 100% recyclable, making it a sustainable choice that supports our environmental values. When you invest in Karmelle machines, you’re investing in a longer-lasting, more environmentally conscious solution.

At the end of the day, our goal is simple: to help our customers succeed. That means providing reliable, efficient, and durable equipment that keeps production running smoothly. By using only premium stainless steel, we build machines our customers can trust, day in, day out.

When you choose Karmelle, you’re choosing a partner that values safety, sustainability, and performance. Our unwavering commitment to quality means our machines are built to meet the highest standards, because your food products deserve nothing less.
