From evaluating your product needs to factoring in long-term costs, these tips will help you make an informed decision that aligns with both your immediate and future goals.
1. Understand Your Product Needs
Tip: Assess the type of pet food you’re packaging (dry, wet, treats) to determine the most suitable packaging machine type.
- Dry vs. Wet:Wet pet food requires packaging that prevents moisture loss, contamination, and spoilage. It might need vacuum sealing or cans. Dry food, on the other hand, often needs moisture barriers and robust seals to maintain freshness.
- Treats: Pet treats often need flexible packaging that can easily be resealed to preserve freshness and prevent odor leakage.
- Supplements and Medicines: These often require tamper-proof, child-resistant, or secure packaging to ensure safety.
2. Evaluate Machine Speed and Efficiency
Tip: Match the machine’s speed with your production demands to ensure efficiency and avoid bottlenecks.
- Machine Speed (Throughput)
Units per Minute (UPM): This is a direct measure of how many units (bags, cans, pouches, etc.) the machine can pack per minute. It’s essential to know your production volume to match it with the machine’s speed.
Formula:
Max Speed vs. Optimal Speed: Always consider both the machine’s maximum speed and the speed at which it operates most efficiently under normal working conditions. Running a machine at its maximum speed constantly might reduce its longevity and increase maintenance costs.
Speed Scaling with Product Variability: The speed can decrease when switching between different product sizes, types, or materials. Machines should have a flexible speed range depending on product changes.
- Efficiency Metrics
Overall Equipment Effectiveness (OEE): OEE is a comprehensive metric that combines three key factors: Availability, Performance, and Quality.
Availability: This measures machine uptime vs. downtime (e.g., maintenance, changeovers).
Performance:This checks if the machine is performing at its intended operational velocity.
Quality: This checks for the number of defective products produced.
Formula:
A good target OEE score is typically around 90% or higher, but this can vary by industry.
Downtime: Track both planned (e.g., maintenance) and unplanned (e.g., machine failure) downtime. Minimizing downtime can significantly improve efficiency.
Planned downtime: Scheduled maintenance, cleaning, or product changeover.
Unplanned downtime: Breakdowns or errors that stop production unexpectedly.
Changeover Time: The time what we need to spend for change product specification. In the pet food industry, you might be switching between different types of packaging or different flavors of pet food. Machines with quick-change features or automated changeover systems are more efficient in minimizing this downtime.10 tips to choose a suitable packaging machine for packaging pet food.
3. Package format
Tip: Choose a machine that can handle multiple packaging formats (pouches, bags, trays, etc.) for future flexibility.
- Flexible Pouches(Stand-up Pouches, Flat Bottom Bags, Pillow Bags, Four-Sided
Sealed Pouch, etc.
Common for: Dry food, treats, and wet food.
Features: Lightweight, space-efficient, resealable, and often equipped with tear notches or spouts.
Benefits: They’re easy to store, keep food fresh with high-barrier materials, and can include features like transparent windows for consumers to see the product.
- Cans
Common for: Wet pet food (e.g., dog and cat food).
Features: Traditional option, sealed to prevent spoilage.
Benefits: Long shelf life, good protection from external elements, and offers a premium, recognizable look. However, they are less environmentally friendly compared to other formats.
- Plastic Containers
Common for: Dry and semi-moist pet food.
Features: Rigid, stackable, and often come with screw-on lids or snap-on closures.
Benefits: Good for bulk food, protects against moisture and contamination, and is highly durable. However, they can be bulky and less eco-friendly.
- Cardboard Boxes
Common for: Dry food (often kibble or biscuits).
Features: Made from recycled paperboard, often with a protective inner liner.
Benefits: A sustainable option, easy to stack, and allows for more colorful branding. However, it’s not as durable against moisture as plastic or metal packaging.
- Tetra Paks
Common for: Wet food, especially liquid or gravy-based pet food.
Features: Sealed and multi-layered cartons for longer shelf life.
Benefits: Lightweight, easy to store, and made from renewable sources, making it more eco-friendly. Tetra Paks also offer excellent protection from light and air, preserving product quality.
4. Look for Precision and Consistency
- Weight/Volume Measurement
Precision Test: Weigh a sample of filled packages at various points during the production run. Measure how each sample’s weight aligns with the established target weight. A precise machine should deliver very similar weights for each package within the tolerance limits. You can also consider adding the check weigher after the packing machine.
5. Consider Packaging Materials Compatibility
Tip: Choose a machine that can work with a range of packaging materials (films, foils, laminates) based on product type and shelf-life needs.
Moisture & Air Resistance: Choose materials that offer strong barriers against moisture, oxygen, and light (such as laminated films or foil-based materials).
UV Protection: Using opaque materials or UV-resistant coatings can help preserve the nutritional value.
- Material Durability
Tear and Puncture Resistance: Pet food packaging should be strong enough to withstand rough handling, storage, and transportation. This is especially important for dry kibble, which can cause packaging to tear if not properly designed.
Impact Resistance: Consider how the packaging will perform if dropped or bumped during handling. Materials like polyethylene or polypropylene can offer more resistance to impacts.
- Food Safety
Non-toxic Materials: Packaging should be made from food-grade materials that are safe for both pets and humans. Look for certifications like FDA approval or compliance with food safety regulations.
No Chemical Migration: Make sure the material is suitable for pet food and free from harmful substances that could pose health risks.
- Sealing & Closure Systems
Seal Strength: A reliable heat-seal or pressure-seal is essential to protect the freshness of pet food and prevent leaks or contamination.
Resealability: Consider whether the packaging needs to be resealable (e.g., for bags of dry food). Zipper closures or fold-over seals can provide convenience for consumers and help maintain product freshness after opening.
- Environmental Impact
Sustainability: Choose packaging materials that are recyclable, biodegradable, or made from recycled materials. This can appeal to environmentally-conscious consumers and help reduce waste.
Lightweight Design: Minimizing the weight of packaging can reduce transportation costs and improve overall sustainability.
