How to Identify the Quality of Kraft Paper Tape
Kraft paper tape is widely used in various industries, but how to distinguish its quality? Here are some key points.
Check the Paper QualityHigh-quality kraft paper tape is usually made from virgin paper. It has a smoother surface and clear textures. In contrast, if it's made from recycled paper, it may feel harder, more brittle and be prone to breakage.
Examine the AdhesionGood kraft paper tape should have strong and stable adhesion. For water-free kraft paper tape, it should stick firmly to the surface without easily falling off. And for wet kraft paper tape, after being wetted, it can form a strong bond quickly. Moreover, there should be no glue residue left after bonding or pasting items. Otherwise, it indicates poor quality.
Assess the ThicknessThe thickness of single-layer kraft tape matters. Measure it with a caliper. Generally, for packaging heavy items, thicker tape is needed to ensure sufficient tensile strength. If the tape is too thin, it may break easily during use1.
Inspect the AppearanceThe surface of high-quality kraft paper tape should be flat and free from tears, gaps, deformation or glue overflow. Joints should be minimal, as too many joints will affect its performance and aesthetics.
Test the Physical PropertiesTensile strength is an important indicator. Try to stretch the tape by hand or use professional equipment for testing. High-quality tape can withstand a certain degree of stretching without breaking. In addition, good kraft paper tape has certain waterproof and weather-resistant properties. You can conduct a simple water test by exposing the tape to water for a period to see if its performance is affected.
By following these methods, one can effectively identify the quality of kraft paper tape and choose the most suitable product for different applications
