How to choose a suitable pet food packaging machine？

Choosing the right pet food packaging machine requires a comprehensive consideration of product form, production capacity requirements, and technical specifications. Key considerations include:

1. Selecting a machine based on packaging format
Pellets/Snacks (Bagged)
Roll Film Packaging Machine: Automatically makes bags, suitable for low- and mid-range packaging such as back-seal bags and gusseted bags, offering low costs.
Pouch-feeding Packaging Machine: Supports pre-made bags (stand-up pouches, zipper bags, and octagonal bags), resulting in high-end, aesthetically pleasing products suitable for a wide range of product categories.
Wet Food/Canned Food (Sealed and Fresh)
A dedicated filling and sealing machine combination is required to ensure vacuum sealing compatibility with high-temperature sterilization to prevent spoilage. Stretch film vacuum packaging machines feature a four-seal design for enhanced sealing and extended shelf life.
Gift Boxes/High-End Products (Boxed)
Pillow or shrink wrapping machines facilitate complex packaging. Folding and Decorating Process
II. Core Performance Indicators
‌Precision Control‌: Weight error must be ≤0.3% (e.g., ±5g for a 10kg packaging machine), and seal strength must be ≥20N/15mm to prevent air leaks.
‌Production Capacity Adaptation‌: Large factories: High-speed, fully automatic models (e.g., double-hopper packaging machines) support flexible production of 5-20kg and thousands of packages per hour.
Small and medium-sized factories: Semi-automatic equipment reduces costs and leaves room for upgrades.
‌Material Compatibility‌: Plastic films (PE/PP) require heat-sealing technology; metal canning equipment requires a pressure-resistant seal design.
III. Optimization for Special Needs
‌Irregular-Shaped Foods: Optional vibrating plate for material handling or customized unloading mechanism.
‌Pastes (e.g., cat strips): Pneumatic filler with a filling accuracy of 1% and a temperature of 140°C to ensure hygiene.
IV. Model Comparison Recommendations
‌Scenario‌ Recommended Machines Advantages
For high-yield pellets (cost-first), we recommend the roll film packaging machine, which offers low investment and fast bag production. For flexible production of multiple specifications, we recommend the dual-hopper quantitative packaging machine, which boasts ±0.3% accuracy with AI algorithm parameter adjustment. For long-term freshness preservation of wet grains, we recommend the four-seal vacuum packaging machine, which offers sterilization compatibility and oxidation resistance.
