Plastic storage boxes are safe for archival purposes
Plastic storage boxes are indeed safe for archival purposes, provided they are made of the right kind of plastic. Polypropylene (PP) and polyethylene (PE) are two types of plastic that have been tested and proven safe for artificial ageing scenarios. These plastics are also effective in preventing damage from humidity and rodents.
When storing textiles, it is important to consider the potential for excess moisture to be trapped in the plastic, especially in humid conditions. Light can also be a factor, as it can easily damage certain materials such as silk. Clear plastic boxes may not be ideal in such cases, as they can let in light.
Acid-free storage boxes are specifically designed for archival purposes, offering a protective and stable environment that prevents decay. They are commonly used to preserve documents, pictures, artwork, and other valuable items, including textiles and garments. Acid-free boxes are effective in blocking dust, dirt, and light, making them ideal for storing items that are vulnerable to acid exposure, such as photographs, documents, and other paper-based collections.
When using plastic storage boxes for archival purposes, it is recommended to use acid-free tissue paper to wrap and separate items, providing an additional layer of protection. It is also important to ensure that the items being stored are clean and free of any embellishments or pins that could cause stains or damage over time. Overall, plastic storage boxes made of polypropylene or polyethylene, coupled with acid-free tissue paper and proper preservation techniques, can provide a safe and effective solution for archival storage.

Acid-free boxes prevent decay and deterioration
Acid-free boxes are designed to prevent decay and deterioration, making them perfect for archival purposes and long-term storage. They are a reliable choice for preserving documents, pictures, artwork, garments, and other valuable items.
Acid-free storage boxes create a protective and stable environment for your items. They block dust, dirt, light, and natural elements that can cause irreversible damage. Humidity, for instance, can cause excess moisture in plastic storage boxes, but acid-free boxes safeguard against moisture. They also prevent yellowing, brittleness, and deterioration caused by acid exposure. This means your items will maintain their structural integrity and original appearance over time.
Acid-free boxes are available in various sizes and styles, making them versatile for different storage needs. For instance, photograph storage boxes often have individual compartments or acid-free envelopes to keep photos from sticking together and causing damage. Art storage boxes feature adjustable lids, dividers, and padding for added protection. Textile and garment storage boxes are spacious and often lined with acid-free tissue paper to protect against moisture, yellowing, staining, and fabric deterioration.
When choosing plastic storage boxes, look for polypropylene or polyethylene, commonly known as PP or PE, respectively. These plastics have been tested and proven safe in artificial aging scenarios. However, if you're looking for a fortress against decay and deterioration, acid-free boxes are the way to go. They are specifically designed to protect your cherished items and keep them in pristine condition for years to come.

They are ideal for storing documents, photos, and artwork
Plastic storage boxes are a great option for storing documents, photos, and artwork. When considering plastic storage boxes, look for polypropylene or polyethylene. Both of these plastics have been tested as safe in conservators' artificial aging scenarios. Polypropylene usually has the initials "PP" on the base under the recycling symbol, while polyethylene products contain a "PE" in addition to other letters (e.g., HDPE, LDPE).
These plastic storage boxes can provide an ideal environment for storing documents, photos, and artwork. They are designed to prevent damage from light, humidity, and other natural elements, which can cause irreversible harm to your valuables. Plastic storage boxes can also come with individual compartments or acid-free envelopes, lids, dividers, and padding for added protection and organisation.
For example, if you are storing photographs, individual compartments or acid-free envelopes can keep each photo from sticking to one another and causing damage. If you are storing artwork, adjustable lids, dividers, and padding can provide extra protection for your artwork.
Additionally, plastic storage boxes can be a good option if you are concerned about rodents or pests. Plastic can provide a protective barrier against pests, which is especially important if you are storing items for a long period.
Overall, plastic storage boxes offer a durable and versatile solution for storing documents, photos, and artwork, helping to preserve your precious items and ensure they stay in good condition for years to come.

Polypropylene and polyethylene plastics are safe for storage
Plastic storage boxes are a convenient and affordable solution for various storage needs. When considering plastic storage boxes, it is essential to prioritize safety and opt for materials that are free from harmful chemicals. Polypropylene (PP) and polyethylene (PE) plastics are two commonly used materials for storage boxes that offer durability and safety.
Polypropylene is a versatile plastic used in a wide range of applications, from food storage containers to rugs and fabric reinforcements. It is considered one of the safer plastic options by organizations like the Environmental Protection Agency (EPA) and is FDA-approved for food contact. Polypropylene containers are identified by the number 5 surrounded by a triangle on the bottom. This plastic exhibits high heat resistance, making it suitable for use in microwaves and dishwashers without leaking toxins. Additionally, polypropylene is chemical-resistant and does not contain Bisphenol A (BPA), a chemical of concern in some plastics that can leach into food and water.
Polyethylene, on the other hand, is known for its safety and non-toxic properties. It is generally safe for food storage, although it should not be left in hot places as UV rays can cause it to break down. Polyethylene containers are marked with "PE" or variations like HDPE and LDPE, which are ranked as safe for food storage. These plastics provide resistance to mold, mildew, and corrosion, preventing toxins from leaching into their contents.
Both polypropylene and polyethylene have been tested and proven safe in artificial aging scenarios, also known as Oddy tests, conducted by conservators. This indicates their durability and suitability for long-term storage. However, it is worth noting that some concerns have been raised about the potential environmental impact of the manufacturing process for plastic products.
When using polypropylene or polyethylene storage boxes, it is important to follow certain precautions. For example, it is recommended to avoid storing fatty or acidic foods in plastic containers, as these can absorb harmful chemicals more easily. Additionally, proper maintenance of plastic items includes hand washing to reduce wear and tear and discarding any scratched or damaged containers.
