Two of the most common materials used in their construction are woven polypropylene (PP) and polyethylene (PE) film. Understanding the core differences between these two material systems is essential for protecting your cargo and optimizing logistics costs.<\/p>\n<p>A <strong>woven PP container liner<\/strong> is typically made from high-density polyethylene (HDPE) or polypropylene woven fabric, often coated with a lamination layer to enhance moisture resistance. The base material is a tightly woven textile that provides high tensile strength and tear resistance. It can be designed with lifting loops, loading spouts, and discharge outlets. Our DBL-W01 and malt-grade DBL-W02 liners are representative examples of this category.<\/p>\n<p>A <strong>PE-Folien-Containerliner<\/strong>, on the other hand, is manufactured from blown or cast polyethylene film\u2014most commonly LDPE (low-density polyethylene). It forms a continuous, seamless barrier with no woven texture. The smooth surface eliminates cargo hang-up, and the film can be made thicker for increased durability. Our DBL-F01 standard PE film liner and the European pellet-focused DBL-F02 are built on this principle.<\/p>\n<p>Both types serve the same fundamental purpose\u2014protecting dry bulk cargo from moisture, contamination, and spillage during transit\u2014but they do so with very different physical properties and application sweet spots.<\/p>\n<h2>Material Structure and Manufacturing<\/h2>\n<p>Woven liners start as extruded tapes that are woven into a fabric, then often coated on one or both sides with a thin layer of PE or PP. This laminated structure combines the tensile resistance of woven fabric with the barrier properties of the coating. Seams are typically stitched and then sealed with heat-sealing tape or over-taping. For powder-grade applications like cement or titanium dioxide, a sift-proof variant with PU tape-sealed seams is used. The woven base gives these liners a distinctive textured feel and high resistance to punctures from sharp-edged cargo.<\/p>\n<p>PE film liners are produced by blowing or casting molten polyethylene into a continuous tube or sheet. The absence of seams on the liner body (side walls and floor are often cut from a single film tube) means there are no stitch holes to seal. Welded seams used for spouts and closures maintain a uniform barrier integrity. The material is inherently flexible and conforms closely to the container walls, which helps during discharge by reducing \u201cbridging.\u201d PE liners can range from 80 to over 200 microns in thickness.<\/p>\n<h2>Physical Performance Comparison<\/h2>\n<table>\n<thead>\n<tr>\n<th>Property<\/th>\n<th>Gewebter PP\/HDPE-Liner<\/th>\n<th>PE-Folien-Liner<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Tensile strength (warp)<\/td>\n<td>1,500\u20132,000+ N\/5cm<\/td>\n<td>1,300\u20131,500 N\/5cm<\/td>\n<\/tr>\n<tr>\n<td>Durchsto\u00dffestigkeit<\/td>\n<td>High \u2013 woven structure distributes point loads<\/td>\n<td>Moderate \u2013 can be punctured by sharp objects<\/td>\n<\/tr>\n<tr>\n<td>Feuchtigkeitsbarriere<\/td>\n<td>98%+ with lamination; breathable uncoated versions available<\/td>\n<td>100% waterproof barrier<\/td>\n<\/tr>\n<tr>\n<td>Dust\/sift resistance<\/td>\n<td>Seam-dependent; PU-taped seams achieve 100% sift-proof<\/td>\n<td>Seamless \u2013 inherently dust-tight<\/td>\n<\/tr>\n<tr>\n<td>Cargo adhesion<\/td>\n<td>Possible on uncoated fabric<\/td>\n<td>Smooth surface reduces adhesion<\/td>\n<\/tr>\n<tr>\n<td>Flexibility at low temperatures<\/td>\n<td>Remains strong, but uncoated fabric may stiffen<\/td>\n<td>Excellent \u2013 PE stays flexible well below 0\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Weight per liner<\/td>\n<td>15\u201350 kg depending on size and coating<\/td>\n<td>15\u201340 kg<\/td>\n<\/tr>\n<tr>\n<td>Wiederverwendbarkeit<\/td>\n<td>Typically single-use; heavy-duty variants reusable 2\u20133 times<\/td>\n<td>Typically single-use<\/td>\n<\/tr>\n<tr>\n<td>Cost per unit<\/td>\n<td>Generally lower for standard grades<\/td>\n<td>Slightly higher for equivalent thickness, but cheaper than complex coated woven<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>How to Choose Between Woven and PE Film Liners<\/h2>\n<h3>Cargo Type Matters Most<\/h3>\n<p>The first and most critical filter is your cargo. Woven liners excel with granular, semi-abrasive, or irregularly shaped materials that could puncture a thin film. Think grains, minerals, cement, soda ash, and plastic pellets. The woven base provides forgiveness if cargo is loaded quickly from height. For malt and other premium grains, double-sided LDPE lamination on woven fabric offers a food-grade moisture barrier while still handling well under high-speed auger loading. Our DBL-W02 malt-grade liner is engineered specifically for this scenario, cutting loading time from hours to 30\u201360 minutes compared to bagging.<\/p>\n<p>cURL Too many subrequests by single Worker invocation.
