Product Introduction

A bulk bag liner (also known as an FIBC inner liner or PE bulk bag liner) is an internal bag designed to fit inside a flexible intermediate bulk container (FIBC) to provide an extra protective layer for powders, granules, flakes and non-hazardous liquids. Der’s bulk bag liners are engineered to enhance product protection against moisture, oxygen, contamination and cross-contact — improving shelf life, handling efficiency and compliance with food, chemical and pharmaceutical supply chains.

Available in single-layer PE film liners, multi-layer co-extruded barrier liners (EVOH/PE), anti-static conductive liners, and food-grade laminated liners, our solutions support diverse application needs: from cement and fertilizer to food ingredients, pigments, and sensitive hygroscopic chemicals.

Product Features

• Multi-material options: HDPE/LDPE blown film, co-extruded PE, EVOH barrier, metallized film, laminated food-grade film.
• Moisture & oxygen barrier: EVOH or metallized layers reduce oxygen transmission and provide an effective moisture barrier for hygroscopic products.
• Food-grade certification: FDA / EC compliant materials and hygienic manufacturing available for food and feed applications.
• Anti-static & conductive liners: For dust-prone powders and flammable materials, we offer antistatic treated and conductive film liners compatible with safety standards.
• Custom fit & easy filling: Tubular liners, bottom-seal or V-shaped seal, top spout or full open top designs to suit automatic filling systems and manual operations.
• Durable sealing & closures: Heat-sealable seams, welded closures, zip-locks, or taped seam options for secure containment.
• Re-sealable & discharge options: Spout bottom, chute bottom or full peel-open designs for controlled discharge.
• Printing & identification: Custom printing, batch codes and traceability labels available to integrate with your logistics and QA processes.

Installation Precautions

1. Verify liner dimensions against your FIBC (length, width, height, spout position) before ordering.
2. When using anti-static liners, ensure both liner and FIBC meet your site's electrostatic control procedures.
3. Avoid sharp edges when inserting liners—use protective guides or smooth chutes.
4. Securely close top and bottom closures per product requirements to prevent contamination and spillage.
5. Train operators on safe filling and discharge, particularly for dusty or flowable powders.
6. Store liners in a clean, dry area away from direct sunlight and chemicals that could degrade film.

Use FAQs

Q1: What is a bulk bag liner and why do I need one?

A: A bulk bag liner is an inner bag placed inside an FIBC to protect the product from contamination, moisture and oxygen, and to facilitate hygienic handling. Liners are essential for food-grade products, hygroscopic chemicals and situations where cross-contact must be avoided.

Q2: Can you make food-grade bulk bag liners?

A: Yes. We offer liners made with FDA and EU-compliant materials and run production on hygienic lines to meet food and feed requirements.

Q3: Do you provide anti-static liners for combustible dusts?

A: We supply surface-treated anti-static and conductive liners; selection depends on dust properties and your site’s electrostatic control plan. Always consult a safety engineer for combustible dust applications.

Q4: How do I choose the right barrier liner?

A: Choose based on product sensitivity to moisture and oxygen. For high moisture/oxygen sensitivity, co-extruded EVOH or metallized barrier liners are recommended. Our technical team can advise after reviewing your product data.

Q5: What custom printing options are available?

A: We provide flexographic and rotogravure printing up to multiple colors for branding, handling instructions, batch codes and traceability marks.
