Advantages of Paperboard Cover

Acid-Free Protection: Acidic materials can cause yellowing, brittleness, and deterioration in paper over time. Paperboard covers are acid-free, which helps prevent these issues and keeps your documents in pristine condition for years to come. This is particularly important for items like family records, legal documents, and photographs, which hold sentimental or historical value.
Durable and Long-Lasting: Made from archival-grade materials, these paperboard covers are built to last. Their robust design ensures that your valuable items stay safe and protected from physical damage, like tears or bending, which can happen in flimsy containers. Durable storage containers are vital for long-term document protection.
Protection from Environmental Factors: Paperboard covers also shield against environmental factors like light, dust, and pollutants. This is crucial for the preservation of documents, as exposure to these elements can cause degradation. Many paperboard covers are designed for use in climate-controlled storage, providing extra protection against humidity and temperature fluctuations.
Climate-Controlled Storage: When combined with proper storage conditions, paperboard covers ensure the safety of your items for decades. For instance, when stored in a climate-controlled storage room, these paperboard covers protect documents from humidity, temperature changes, and even pests, which can otherwise lead to mold, mildew, or other forms of decay.
Cost-Effective Long-Term Solution: While archival storage solutions may have a higher upfront cost, they are an investment in the long-term protection of your valuable documents. By safeguarding them against deterioration, you can avoid the need for expensive restoration or replacements down the line.
Paperboard Cover Material Types
Corrugated Cardboard
They have high crush resistance due to a double wall or triple wall structure. You can request to change the flute. In the high humid environment, don’t use corrugated paperboard coveres as they are highly susceptible to moisture, leading to deterioration against stacked with heavy loads.
Acid Free Archive Paperboard Covers
Paperboard covers are made of cardboard, but they’re chemically stable due to being buffered to neutralize environmental acid. When it comes to strength, paperboard covers are comparable to corrugated paperboard coveres. These paperboard covers have a longer lifespan of 50-100 years but require periodical inspection after every 5-10 years.
Polypropylene or Polyethylene Archive Packaging
They are good for a 5-10 year lifespan and have superior resistance to water, pests, and mold. Our archive packaging can survive against physical impact as well. They have high chemical stability, but at fluctuating temperatures, these packages cause a condensation effect.

Paperboard Cover Proper Placement And Storage Settings
Paperboard covers work best in stable environments. Store Paperboard covers away from direct sunlight—UV rays break down paper and ink. Temperatures between 60–70°F (15–21°C) and humidity from 30–50% help stop mold, mildew, and pests.
Don’t set covers on the floor, especially in basements or attics. Use shelves or pallets to let air circulate and keep water or pests away. If you can, keep covers away from exterior walls, windows, and heat sources.
