We carefully select trusted materials for our courier bags—PP for cost-efficiency, PE for lightweight reliability.
This ensures your courier bags provide superior protection, resist tears, and withstand the demands of tough shipping conditions.
With Allpaperbag, you get reliable, customizable courier solutions that safeguard your shipments, enhance your brand’s professionalism and deliver confidence with every package.
We implement rigorous in-process quality control measures during production to ensure that every product meets your requirements.
Every courier bag is tested on an Instron 3300 Series tensile machine to measure strength and elongation under load.
This ensures each bag can withstand weights up to 20kg without tearing.
Our bags are measured using the Mitutoyo Surftest SJ-210 to verify uniform thickness down to ±0.01mm.
This guarantees consistent material quality and reliable performance during shipping.
Integrated Keyence CV-X Series AI vision systems inspect every bag for micro-tears, uneven seams, or printing errors at a speed of 300 units per minute, ensuring defect-free batches.
Courier bags undergo stress tests in an Espec Platinous PH Series Environmental Chamber, simulating extreme temperatures (-20°C to 60°C) and humidity levels (up to 95%).
This ensures durability across diverse climates.
At ProtegoSeal, we use advanced testing equipment to ensure every security seal meets the highest standards. From tensile strength to tamper-evidence and environmental durability, our rigorous checks deliver seal consistency.
You can trust us to handle all certification requirements. Our products meet rigorous standards, knowing your security seals are fully compliant and reliable.
