Dissolvable Flat Bags & Box Liners

Water-soluble flat bags and box liners that dissolve completely in hot water. Zeropac's dissolvable packaging eliminates waste sorting in food manufacturing, supports EO sterilisation processes in medical applications and provides cement additive packaging for construction across Australia.

Available as flat bags for EO sterilisation and chemical packaging, carton liners for food processing and gusseted box liners for secure carton lining. Australian stock ensures fast delivery when you need restocks urgently.

Water-Soluble Packaging That Saves Time and Eliminates Waste

Dissolvable flat bags and box liners dissolve completely in hot water, eliminating the need to separate packaging from contents. Food processors skip the liner removal step, medical facilities streamline sterilisation workflows and construction suppliers eliminate packaging waste from cement additives.

The PVOH (Polyvinyl Alcohol) film dissolves within minutes of hot water contact, leaving no plastic residue and significantly reducing processing time across food manufacturing, medical sterilisation and building material applications.

Two Product Types for Different Applications

Time Savings in Food Manufacturing

The primary benefit of dissolvable carton liners and box liners in food processing is eliminating waste sorting time. Traditional plastic liners require manual separation from food contents before processing or disposal. Workers spend valuable time removing liners from cartons, creating labour costs and slowing production.

With water-soluble liners:

• No liner separation required - Contents go directly to processing with liner intact
• Faster throughput - Skip the manual liner removal step entirely
• Reduced labour costs - Eliminate time spent separating packaging from contents
• Less waste handling - No plastic liner disposal required
• Cleaner processing - Liners dissolve completely, leaving no contamination

Food manufacturers report significant labour savings when switching from traditional plastic liners to dissolvable alternatives, with processing times reduced by eliminating the sorting stage. Learn more about how water-soluble liners eliminate waste sorting in food manufacturing operations.

EO Sterilisation Applications

Dissolvable flat bags support ethylene oxide (EO) sterilisation workflows in medical facilities and sterilisation services. The water-soluble PVOH film allows EO gas penetration for effective sterilisation while providing a protective barrier for medical devices and instruments.

Medical sterilisation benefits:

• EO gas permeable - PVOH film allows sterilisation gas penetration
• Protective barrier - Maintains sterile field until point of use
• Dissolves in processing - Eliminates packaging waste after sterilisation
• Streamlined workflow - No need to remove bags before instrument processing

Cement Additive Packaging for Construction

Pre-measured cement additives packaged in dissolvable flat bags simplify construction workflows. Workers add the entire sealed bag directly to concrete mixers where hot water dissolves the packaging, releasing measured additives without manual opening or waste handling.

Construction industry benefits:

• Pre-measured accuracy - Each bag contains exact additive quantities
• No manual opening - Throw entire bag into mixer
• Zero packaging waste - PVOH dissolves completely in mix water
• Faster mixing - Eliminate bag opening and disposal steps
• Cleaner sites - No plastic packaging waste to collect

How Water-Soluble Packaging Works

Dissolution process:

1. Hot water contact: PVOH film begins dissolving at 60°C or higher
2. Complete dissolution: Packaging dissolves within 3-5 minutes
3. Contents released: Food, instruments or additives are freed for processing
4. No residue: PVOH biodegrades completely, leaving no plastic waste
5. Zero sorting: No need to separate packaging from contents

Eco-Friendly Packaging Benefits

Water-soluble packaging delivers environmental advantages alongside operational efficiency:

• Eliminate plastic waste - PVOH biodegrades completely, leaving no microplastics
• Reduce landfill - No plastic packaging requiring disposal
• Lower carbon footprint - Eliminate transport and disposal of plastic waste
• Compostable - PVOH breaks down into water, carbon dioxide and biomass
• Marine-safe - If packaging enters waterways, it biodegrades without harming marine life

Food processors, medical facilities and construction suppliers reduce environmental impact while improving operational efficiency through elimination of plastic packaging waste.
