Advanced Moisture-Proof Packaging Solution for Superior DTF Film Protection During Storage and Transportation

SAILLAGE's upgraded DTF film packaging combines a double-end waterproof-laminated paper core, an aluminum foil PE moisture barrier film with up to 80% stronger humidity resistance, two high-efficiency desiccant packs inside every carton, and a reinforced 70-micron PET outer bag — a four-layer system that protects DTF film rolls from internal and external humidity from the

 factory floor through long-distance storage and international transportation.

For DTF film (direct-to-film) printing applications, maintaining consistent film quality during storage and transportation is essential. As a key material in the DTF printing process, DTF film requires excellent dimensional stability, surface performance, and moisture resistance to ensure reliable printing results.

Humidity fluctuations during logistics can affect DTF film quality, including film stability, surface properties, printing performance, and processing efficiency — which may cause the ink to bleed while printing and the powder to stick to the DTF film. These challenges become more significant during international transportation, long-distance shipments, and storage in high-humidity environments.

To provide better protection for DTF film products, Shanghai Saillage International Trade Co., Ltd. has developed an upgraded moisture-proof packaging solution featuring multiple advanced protection technologies. This improved packaging system creates a stronger humidity barrier against both internal moisture sources and external environmental conditions.

The enhanced DTF film packaging structure combines waterproof paper core protection, upgraded moisture barrier materials, active moisture absorption, and reinforced outer packaging. Together, these improvements help ensure DTF film reliability from factory delivery to final customer application.

The Four-Layer Moisture Protection System at a Glance

1. Waterproof Paper Core Protection for DTF Film Rolls

Double-End Laminated Paper Tube Structure

The paper core is an important supporting component of DTF film rolls and can become a potential pathway for moisture penetration during storage and transportation. To reduce this risk, the traditional paper tube structure has been upgraded by adding a waterproof laminated layer to both ends of the paper core.

This enhanced design helps prevent moisture from entering through the tube openings and provides an additional protective barrier for DTF film rolls.

Main advantages:

• Prevents humidity from entering through both ends of the DTF film paper core.

• Protects DTF film performance during long-distance transportation.

• Helps maintain stable peeling performance and printing quality.

2. Enhanced Moisture Barrier Film for DTF Film Packaging

Aluminum Foil PE Barrier Structure for Stronger Humidity Resistance

Compared with conventional PE packaging film, the upgraded DTF film packaging system uses an aluminum foil laminated PE barrier film structure, providing stronger resistance against water vapor transmission.

By replacing the traditional PE moisture barrier layer with an aluminum foil PE laminated structure, the packaging achieves improved moisture protection performance and creates a stronger defense against humidity.

Moisture resistance improvement: up to 80% enhanced moisture resistance.

Key benefits:

• Superior water vapor blocking performance for DTF film storage.

• Reduced moisture absorption during DTF film transportation and storage.

• Better protection for DTF film in high-humidity environments.

3. Additional Moisture Absorption Protection for DTF Film Packaging

Two High-Efficiency Desiccant Packs Inside Each Carton

Besides external moisture barrier protection, active humidity control has been added inside the DTF film packaging.

Each carton is equipped with two packs of high-efficiency desiccant, which actively absorb residual moisture inside the package environment and provide additional protection during transportation and long-term storage.

Benefits:

• Provides additional humidity control for DTF film.

• Reduces moisture accumulation during transportation.

• Improves long-term DTF film storage stability.

4. Reinforced PET Moisture-Proof Bag for DTF Film Rolls

Upgraded 70-micron PET Packaging Structure for Stronger Durability

To further improve DTF film packaging reliability, the outer moisture-proof bag has been upgraded from the traditional 50-micron PET structure to a stronger 70-micron PET moisture-proof bag.

Compared with the traditional 50-micron PET bag, the upgraded 70-micron structure increases thickness by 40%, providing stronger mechanical protection and improved packaging durability for DTF film rolls.

Key benefits:

• Stronger puncture resistance for DTF film packaging.

• Better sealing durability.

• Enhanced protection against external humidity.

Complete Moisture Protection System for Global DTF Film Transportation

During international logistics, moisture-related problems can create unexpected risks for DTF film quality. A reliable packaging solution is not only designed to prevent water exposure, but also to maintain product consistency, reduce transportation risks, and ensure stable DTF film performance when products arrive at the customer's facility.

With the upgraded moisture-proof packaging system, every DTF film roll receives comprehensive protection through:

• Waterproof paper core protection — the double-end laminated paper tube keeps moisture away from the roll ends.

• High-performance aluminum foil PE moisture barrier film — up to 80% stronger resistance against water vapor transmission.

• Dual desiccant humidity control — two high-efficiency desiccant packs actively absorb residual moisture inside every carton.

• Reinforced 70-micron PET outer packaging — a 40% thicker bag with stronger puncture resistance and sealing durability.

Through continuous improvement in packaging technology, Shanghai Saillage is committed to providing safer, more reliable, and more professional packaging solutions for DTF film customers worldwide.

Better protection. More stable DTF film quality. Greater confidence throughout storage and transportation.

Frequently Asked Questions

Why does DTF film need moisture-proof packaging?

DTF film must keep consistent dimensional stability, surface performance, and moisture resistance to print reliably. Humidity fluctuations during storage and logistics can trigger problems such as ink bleeding during printing and powder sticking to the film, so moisture-proof packaging is essential to protect film quality from the factory to the customer.

How does humidity affect DTF film quality?

Humidity can affect film stability, surface properties, printing performance, and processing efficiency. In practice this can cause ink bleeding while printing and powder sticking to the DTF film, with the risks becoming more significant during international transportation, long-distance shipments, and storage in high-humidity environments.

What makes up the upgraded DTF film moisture-proof packaging?

The upgraded system has four protection layers: a double-end waterproof laminated paper core, an aluminum foil PE moisture barrier film, two high-efficiency desiccant packs inside each carton, and a reinforced 70-micron PET outer bag.

How much stronger is the aluminum foil PE barrier than conventional PE film?

Replacing the traditional PE moisture barrier layer with an aluminum foil PE laminated structure achieves up to 80% enhanced moisture resistance, providing superior water vapor blocking and better protection for DTF film in high-humidity environments.

Why are the paper core ends laminated with a waterproof layer?

The paper core ends are a potential pathway for moisture to enter a DTF film roll. Adding a waterproof laminated layer to both ends stops humidity entering through the tube openings, which protects film performance during long-distance transportation and helps maintain stable peeling performance and printing quality.

What changed in the outer PET moisture-proof bag?

The outer bag was upgraded from a traditional 50-micron PET structure to a stronger 70-micron PET moisture-proof bag — a 40% increase in thickness that provides stronger puncture resistance, better sealing durability, and enhanced protection against external humidity.
