As a core raw material in food, pharmaceutical, daily chemical and other fields, edible glycerin, with its characteristics of high purity, strong hygroscopicity and non-corrosiveness, places strict requirements on the safety, sealing performance and stability of storage and transportation links. Traditional storage and transportation methods are prone to pain points such as contamination, loss and high costs. The emergence of dedicated food-grade flexitanks has tailor-made an efficient, safe and economical storage and transportation solution for edible glycerin.

I. Strict Food-Grade Standards, Building a Solid Safety Barrier

Edible glycerin is directly related to the safety of food and pharmaceutical products, so the materials and craftsmanship of flexitanks must comply with the highest-level food contact standards. Our dedicated flexitanks for edible glycerin are made of 100% imported food-grade polyethylene (PE) raw materials. Certified by authoritative institutions, they fully meet the food safety management system certification, eliminating the risk of contamination caused by material migration from the source.

The bag body adopts a multi-layer composite seamless welding process. The inner bag is made of multi-layer food-grade PE film, and the outer bag is made of high-strength polypropylene (PP) woven cloth, forming a dual structure of "sealing protection + impact resistance". It can effectively block air, moisture and external impurities, avoiding moisture absorption, caking and purity reduction of edible glycerin. Each batch of flexitanks undergoes 12 special tests including microbial content, sealing performance and tensile strength, and is equipped with a unique production traceability code, enabling full traceability from raw material procurement, production and processing to finished product delivery. Coupled with product liability insurance, it provides an extra layer of protection for the safe storage and transportation of edible glycerin.

To meet the cleanliness requirements of edible glycerin, flexitanks undergo aseptic treatment before leaving the factory, with no odor or residue, and can be used directly without additional cleaning. This completely avoids cross-contamination caused by incomplete cleaning of traditional containers, guarding the original purity of edible glycerin.

II. Highlighted Core Advantages, Adapting to Edible Glycerin Storage and Transportation Needs

Compared with traditional containers such as steel drums and IBC tanks, dedicated flexitanks for edible glycerin have achieved all-round breakthroughs in safety, economy and efficiency, accurately matching the large-volume, long-distance and high-demand storage and transportation scenarios of edible glycerin.

 (I) Sealing and Moisture-Proof, Maintaining Purity

Edible glycerin is highly hygroscopic. Once exposed to air, it is prone to moisture absorption and dilution, affecting product concentration and quality. The dedicated flexitank adopts an integrated sealing design, equipped with food-grade sealed valves that open and close tightly without leakage. It can effectively isolate air and moisture, ensuring that the concentration of edible glycerin remains stable and the purity meets standards during storage and transportation. At the same time, the bag body has excellent low-temperature resistance, maintaining stable performance in the environment of -20℃ to 60℃, adapting to the transportation needs of different regions and seasons, and avoiding the impact of temperature changes on glycerin quality.

 (II) Cost Reduction and Efficiency Improvement, Optimizing Full-Process Costs

In terms of cost control, flexitanks show incomparable advantages over traditional containers. Taking a 20-foot container as the carrier, a single dedicated flexitank for edible glycerin can have a volume of 24m³, capable of loading 22 tons of edible glycerin. Compared with 80 200-liter steel drums, the loading capacity is increased by 40%, while the packaging cost is only 20% of that of steel drums. In the transportation link, flexitanks do not require empty container return fees, saving the cleaning, maintenance and storage costs of steel drums and IBC tanks. Taking a single cross-provincial transportation of 22 tons of edible glycerin as an example, the total cost can be saved by more than 7,000 yuan.

During the storage phase, unused flexitanks can be completely folded for storage, greatly reducing the cost of site occupation. In the loading and unloading link, paving can be completed by 2 people in 30 minutes, filling in 1 hour and unloading in 30 minutes, which is 60% more efficient than steel drum loading and unloading. No auxiliary tools such as forklifts or cleaning equipment are needed, greatly reducing labor and equipment investment.

 (III) Flexible Adaptation, Supporting Multi-Scenario Circulation

Dedicated flexitanks for edible glycerin are perfectly compatible with road-rail-sea multimodal transportation. Relying on the global container network, they can realize "door-to-door" one-stop transportation without transshipment and repackaging, reducing loss and contamination during handling. To meet the bulk shipment needs of edible glycerin manufacturers, customized volume design is available, adapting to requirements from 15m³ to 26m³. At the same time, it is equipped with food-grade connectors and pipelines to ensure that the filling and unloading processes are closed and aseptic, complying with the norms of the food and pharmaceutical industries.

III. Wide Application, Empowering Quality Upgrade in Multiple Fields

Today, dedicated flexitanks for edible glycerin have been deeply used in core fields such as food, pharmaceutical and daily chemical industries, becoming the standardized storage and transportation choice of leading enterprises in the industry: in the food industry, they transport edible glycerin for manufacturers of candies, pastries, beverages, etc., guarding the purity of raw materials throughout the process and ensuring product taste and safety; in the pharmaceutical industry, they adapt to the storage and transportation needs of pharmaceutical-grade glycerin, helping the compliance of drug production; in the daily chemical industry, they provide safe circulation guarantee for glycerin raw materials of skin care products, toothpaste and other products, avoiding impurities affecting product quality.

With professional products and services, we will become your reliable partner in smoothing the storage and transportation links and enhancing core competitiveness, jointly building a new ecosystem for the pure circulation of edible glycerin.
