Selecting the right food grade pouch can make or break your product’s success in the market. Are you considering food grade pouches but unsure what factors to prioritize? Let’s dive into the essential elements to ensure your packaging meets all the demands of quality, compliance, and customer appeal.
Step 1: Loading the Roll Film
We start by loading the roll of film onto the machine’s feeder. The film is secured tightly with a low-pressure wide tape to prevent any slack. It's crucial to rotate the roll counterclockwise, ensuring a smooth feed into the machine.
Step 2: Guiding the Film with Rollers
Next, rubber rollers gently pull the film forward, guiding it into the correct position. This keeps the film moving smoothly and avoids unnecessary tension.
Step 3: Reeling the Material
Two collection rollers alternate in gathering the material, helping maintain an uninterrupted flow. This step ensures that production remains efficient and consistent.
Step 4: Precise Printing
With the film in place, printing begins. Depending on the design, we use either flexographic or gravure printing. Flexographic printing works well for simpler designs with 1–4 colors, while gravure is ideal for more complex images, capable of handling up to 10 colors. The result is a crisp, high-quality print that’s true to your brand.
Step 5: Controlling Print Accuracy
To maintain precision, a tracking machine monitors the film’s movement and adjusts for any print errors within 1mm. This ensures that logos and text are perfectly aligned, even on large runs.
Step 6: Maintaining Film Tension
A tension control device ensures the film stays taut throughout the process, avoiding any wrinkles that could compromise the final product’s appearance.
Step 7: Smoothing the Film
Next, the film passes over a stainless steel pause plate, which smooths out any creases. This ensures that the film maintains its correct width, crucial for forming the pouch.
Step 8: Laser-Tracking the Cut Position
To ensure precise cuts, we use an 'eye mark' feature that tracks color changes on the printed film. For more detailed designs, white paper is placed beneath the film to enhance accuracy.
Step 9: Sealing the Sides
Once the film is properly aligned, heat-sealing knives come into play. They apply pressure and heat to form a strong, reliable seal on the sides of the pouch. A silicone roller helps the film move forward smoothly during this step.
Step 10: Fine-Tuning Seal Quality
We routinely check the seal quality to ensure it’s consistent and strong. Any slight misalignments are adjusted immediately, keeping the process running smoothly.
Step 11: Static Removal
As the film moves through the machine, special anti-static rollers prevent it from sticking to the machinery. This ensures that the film continues to flow smoothly without delays.
Step 12: Final Cutting
The cutting machine uses a sharp, fixed blade to slice the film with precision. To keep the blade in optimal condition, we regularly lubricate it, ensuring a clean and accurate cut every time.
Step 13: Folding the Pouches
At this stage, the film is folded depending on whether the logo or design should appear on the inside or outside of the pouch. The direction of the fold is adjusted based on client specifications.
Step 14: Inspection and Testing
Quality control is key. We carefully inspect every batch for print alignment, seal strength, and overall quality. Tests include pressure resistance, drop tests, and tear resistance, ensuring that each pouch meets our rigorous standards.
Step 15: Packaging and Shipping
Finally, the pouches are packed and prepared for shipping. Depending on the client’s requirements, we pack them in plastic bags or cartons, ensuring they arrive in pristine condition.
