Product Q&A
Q:What products are best suited for 3-in-1 bags?
A:
3-in-1 bags are recommended for moisture-sensitive and high-value dry powders: cement, dry mortar, tile adhesive, putty powder, gypsum, chemical powders, starch, flour, and other hygroscopic materials requiring maximum moisture protection.
Q:What sizes are available?
A:
Standard capacities include 15kg, 20kg, 25kg, 40kg, and 50kg. Width ranges from 380mm to 620mm with customizable lengths. Custom sizes can be produced to your exact specifications.
Q:What valve types are available for 3-in-1 bags?
A:
We offer 6 valve configurations: left-side internal valve, right-side internal valve, left-side external valve, right-side external valve, left-side ultrasonic valve, and right-side ultrasonic valve. The valve type is selected based on your filling machine specifications.
Q:How does the moisture protection compare to standard PP valve bags?
A:
3-in-1 bags provide 5-star moisture protection thanks to the PE film layer, which creates a near-complete water vapor barrier. Standard PP valve bags offer 3-star protection. For products stored in humid environments or requiring long shelf life, 3-in-1 bags are strongly recommended.
Q:Can the bags be custom-printed?
A:
Yes. The kraft paper outer layer provides excellent printability. We offer up to 5-color flexographic printing with vibrant, durable results. Artwork files in AI, CDR, or PDF format are accepted.
