To ensure the safety and reliability of heavy-duty pet food packaging bags during transportation, handling, and everyday use, we conduct standardized drop tests on every production batch.

These tests follow strict industry guidelines to simulate real-life handling and assess the impact resistance of the bags.

Purpose of the Test:

To verify that the bag can withstand drops without rupturing.
To ensure sealing integrity and prevent leakage.

To improve product safety during logistics and increase customer satisfaction.

Testing Procedure:

A packaging bag filled with 10kg (or designated weight) of pet food is sealed securely.

Using a drop test machine, the bag is dropped freely from various angles (front, back, sides, top, bottom, and corners).

Standard drop height is 76 cm (approx. 30 inches), in accordance with ISO and ASTM guidelines. For some clients, tests are conducted up to 100 cm.

After the drop, the bag is examined for tears, leakage, or broken seals.

Acceptance Criteria:

The sample passes the test if no rupture, leakage, or seal failure is observed after the drop.

What's the key point to make a good quality powder bag?

The quad seal pouch machine is generally longer than other packaging machines because of the additional steps required to form and seal a quad seal pouch. Here are some key reasons:

Additional Sealing Stations: Quad seal pouches require seals on all four vertical edges, which adds structural strength and a more rigid shape. This involves more sealing steps than typical two-sided seals, meaning the machine needs extra sealing stations and length to accommodate this process.

Complex Folding and Forming Process: Quad seal pouches require precise folds and alignment for each edge seal. The machine includes specialized stations to fold and position the material accurately, which extends its overall length.

Enhanced Material Handling: As quad seal pouches are often used for premium products, the machine needs to handle thicker or multi-layered materials that improve durability and barrier properties. This may require additional material handling and support along the machine's length to maintain quality.

Customization Features: Many quad seal pouch machines are equipped with options for adding resealable zippers, valves, or other custom features. Each of these features can require additional space on the machine.

In summary, the additional length accommodates the multiple sealing steps, material handling, and optional features that are typically associated with high-quality quad seal pouches.

The suitable storage conditions for plastic packaging bags:

1. Temperature: Store in a cool place, ideally between 15°C and 25°C (59°F to 77°F), to prevent the plastic from becoming brittle or deforming.

2. Humidity: Maintain a dry environment with a relative humidity of around 50% to 60% to avoid moisture absorption, which could weaken the plastic.

3. Light Exposure: Protect from direct sunlight and strong artificial light, as UV radiation can degrade the plastic, leading to discoloration or brittleness.

4. Ventilation: Ensure the storage area is well-ventilated to prevent any buildup of fumes that might be emitted by the plastic over time.

5. Pressure: Avoid placing heavy objects on the bags to prevent crushing or distortion of the plastic material.

6. Keep away from open flames

These conditions will help maintain the quality and durability of plastic packaging bags. ☺☺
