Industrial packaging is not one-size-fits-all. Powders behave differently from granules, cement requires different moisture control than fertilizers, and automated filling lines demand packaging that seals fast and stays stable in transport. At YINGTONG, we focus on industrial bag structures that protect product quality, run efficiently on packing equipment, and present clean, consistent branding at scale.
Kraft paper valve bags are designed for fast, dust-controlled filling through a corner valve. They are widely used for powdery and granular materials where production speed, clean handling, and reliable closure matter.
YINGTONG supplies 2-ply and 3-ply kraft valve bag options, allowing you to balance burst strength, stiffness, and cost based on your product density and logistics conditions. Typical configurations can be matched with different valve styles, bag dimensions, and printing requirements to support both manual handling and automated packing workflows.
For products that are sensitive to humidity or require enhanced leak resistance, a kraft paper bag with a PE liner provides an extra protection layer without losing the handling feel of paper packaging.
YINGTONG offers 2-ply, 3-ply, and 4-ply kraft constructions with PE liner options. This structure is commonly selected when:
Long-distance transport increases exposure to temperature swings and condensation risk
Fine powders demand stronger internal containment
Customers need a cleaner outer appearance with reinforced moisture control
The liner choice and thickness can be aligned with your filling temperature, product flowability, and storage duration requirements.
For tough handling, strong tear resistance, and stable performance in demanding environments, woven polypropylene (WPP / PP woven) valve bags and related woven structures are a practical solution. These bags are often selected for heavy materials and high-throughput packing lines, especially when packaging must resist puncture, friction, and rough stacking.
YINGTONG’s woven bag solutions can be paired with different surface treatments and constructions, including laminated options when you need improved moisture resistance and cleaner graphics.
Building materials bring special requirements: heavy loads, abrasive contents, and high sensitivity to moisture during storage. YINGTONG develops packaging structures suitable for cement and related construction materials, including valve-style solutions designed to support efficient filling and reliable sealing.
Depending on your plant equipment and distribution model, we can recommend the best balance between paper-based valve bags, paper-plus-liner structures, and woven options to improve stacking stability, reduce damage rates in transit, and maintain a consistent appearance at retail or project sites.
Some products require flexible packaging with straightforward sealing and dependable toughness. YINGTONG provides polythene / polyethylene-based industrial packaging bags used in common industrial workflows such as storage, internal transfer, and shipping preparation.
These solutions are often chosen for products that benefit from:
Simple handling and sealing
Moisture resistance
Cost-effective packaging at volume
Material thickness, bag sizing, and printing can be configured based on how the bag will be filled, stored, and transported.
Below is a practical way to match bag structures to typical operational needs:
| Bag Type | Best For | Key Strengths | Common Options |
|---|---|---|---|
| Kraft Paper Valve Bag | Powders and granules on packing lines | Fast filling, clean handling, stable stacking | 2-ply, 3-ply, custom sizes, printing |
| Kraft Paper Bag with PE Liner | Moisture-sensitive powders | Improved moisture barrier and containment | 2–4 ply kraft, PE liner customization |
| WPP Valve Bag / PP Woven Bag | Heavy products and demanding logistics | Tear resistance, puncture resistance, durable handling | Valve structure, laminated surfaces, printing |
| Building Material Packaging Bags | Cement and construction materials | Load stability, transport durability, production efficiency | Paper, paper+liner, woven structures |
| Polyethylene / Polythene Industrial Bags | General industrial packaging and storage | Moisture resistance, flexible use, cost control | Thickness, sealing style, dimensions |
Industrial packaging must work on the floor, not just look good on a sample. YINGTONG supports customization that aligns with your process, including:
Bag dimensions and volume matched to target fill weight and pallet patterns
Valve design and placement to suit your packing machine interface
Layer structure selection to balance stiffness, strength, and barrier performance
Printing and identification for product information, handling marks, and branding consistency
Material and liner configuration based on moisture risk, powder fineness, and storage conditions
When packaging is treated as part of your production system, small improvements add up quickly. YINGTONG is set up to supply industrial bag solutions with:
Focused product range built around industrial bag structures such as kraft valve bags, kraft bags with plastic liners, and woven valve bags
Structure-first engineering mindset, helping you choose ply count, liner configuration, and bag design based on handling and logistics reality
Flexible customization to match equipment, palletization, and labeling needs
Consistent supply and communication, supporting repeat orders and specification stability across batches
To suggest the most suitable bag type and structure, we typically evaluate:
Product form (powder, granule, mix), bulk density, and flow behavior
Target fill weight and packing speed
Moisture exposure risk across shipping and storage
Pallet pattern, stacking height, and handling method
Print requirements and surface preference
If you share your product type, fill weight, and packing method, YINGTONG can recommend a bag structure that fits your operation and reduces avoidable packaging issues from day one.
