Introduction

Frozen Liquid BIB Packaging is a niche application for products requiring long-term storage or shipment in a frozen state. Suzhou Jingle Packaging provides liners using specialized low-density polyethylene (LLDPE) or co-polymers that maintain their flexibility and integrity at temperatures down to -35掳C. Standard PE films become brittle and prone to failure at these low temperatures. The bags are designed to safely contain the product during both the expansion phase (freezing) and the subsequent thawing/handling phases.

This ensures product safety and prevents costly leaks in the frozen supply chain.

Specification

Temperature Range	Safe storage and handling from 4^circ C down to -35^circ C
Film Material	LLDPE or specialized co-polymer (High puncture resistance at low temp)
Impact Resistance	Tested to withstand sharp impact shock at freezing point
Volume Range	Typically 10L to 220L (Bulk freezing applications)
Filling State	Must be filled cold (ambient or chilled) before freezing

Logistics & Global Compatibility

Cold Chain Durability: Bags maintain strength and resist abrasion during harsh handling in cold storage and freezer trucks.
International Standard: Used globally in the industrial food ingredient trade for safe, long-distance bulk freezing.
Thaw and Use: Compatible with common thawing methods (e.g., warm room) and standard industrial pumping systems once thawed.
Material Certification: All materials are certified for food contact and meet the non-brittleness requirement for frozen logistics.

FAQ

Q: Should I use a barrier film for frozen liquids?
A: Oxygen is less of a concern when frozen, but a barrier may be beneficial to protect the product during the thawing phase and if stored for any time before freezing.

Q: How full should the bag be filled before freezing?
A: Bags must be filled below 100% capacity (typically 95%) to allow for the expansion of water-based liquids during the freezing process.

Q: Do I need a special filler for frozen liquid bags?
A: No, the bags are filled using standard cold-fill equipment. The key is to control the filling volume and the subsequent freezing rate.

Advantages

Freezing Integrity: Prevents cracking and seal failure associated with standard plastics at sub-zero temperatures.
Space Efficiency: Frozen blocks (when correctly shaped by the outer container) are easier to stack and store than round drums.
Reduced Oxidation: Freezing naturally halts the oxidation process, but the bag's seal maintains product quality during thawing.
Complete Evacuation: Flexible material ensures minimal product clings to the bag walls once thawed.

Application

High-Value Purees: Fruit or vegetable purees frozen in bulk for ingredient use.
Liquid Egg Products: Freezing whole egg, whites, or yolks for extended microbiological life.
Frozen Concentrates: Bulk beverage concentrates or stocks for global transport.
Specialty Food Bases: High-value bases used in the food service industry.
