When using PP woven bags (polypropylene woven bags) as dog food packaging, you need to consider durability, sealing and brand display. The following are specific steps and precautions:

1. PP woven bag customization steps
(1)Material selection and specifications
Material: Choose food-grade PP woven cloth (must comply with GB/T 8946 standard), and the inner layer can be coated with PE or AL to enhance moisture resistance.
Weight: 80-120g/m² (load-bearing 5-20kg) is recommended, and the thickness is 0.08-0.12mm.
Bag type: open bag (bottom sewn) + liner bag (independent seal), or directly make valve bag (convenient for automatic filling).
(2)Printing design
Printing method: use flexible printing (suitable for the rough surface of woven bags, low cost) or lamination color printing (brighter colors, but high price).
Content: brand LOGO, dog food ingredients, net weight, production date, QR code, etc., and a barcode position must be reserved.
(3)Processing technology
Seam: three-strand seam bottom (anti-burst), or heat-sealed edge (special equipment required).
Sealing: can be matched with self-sealing strips, zippers or heat-sealed seals (need to test the sealing).
(4)Testing and acceptance
Sampling for load-bearing test (hanging for 24 hours after filling), moisture-proof test (placed in a high humidity environment for observation).
(5)The ink must comply with food contact material standards (such as FDA or EU 10/2011) to avoid heavy metal migration.
If the inner layer is PE coating, it must be confirmed that there is no odor.
(6)Cost control
The minimum order quantity is usually more than 1,000 pieces, and the cost of each piece is about 0.1-0.3 $ (depending on the process).
Simple design can reduce color matching and reduce plate making costs.
2. Comparison of applicable scenarios
Type Advantages Disadvantages
Ordinary PP woven bags Low cost, strong tear resistance Poor moisture resistance, need to be matched with inner bags
Laminated color printed bags Good waterproofness, exquisite printing High price, poor environmental protection
Valve bags High automated filling efficiency Requires special equipment, not suitable for small batches
