What You'll Learn
Plastic bags can retain heat and cause damage
Plastic bags are not the best option for storing silver. While some people store silver in plastic bags without any issues, plastic contains sulfur and traps moisture, both of which can cause tarnishing. Additionally, plastic bags are derived from petroleum products and contain volatile compounds. When exposed to changes in temperature and humidity, these compounds can leach out onto the silver.
Plastic bags can retain heat, which can cause damage to the items stored inside. Heat sealing is a common practice in the manufacturing and food industries, as it provides a complete seal that can prolong the exposure of food to heat lamps. However, in the context of storing silver, the retention of heat within a plastic bag can be detrimental. As plastic ages, it can off-gas sulfur and acidic fumes that can leave permanent marks on the metal stored inside. This is especially true if the plastic bag is exposed to high temperatures, as the release of gaseous compounds can increase.
Furthermore, plastic bags themselves can be susceptible to heat damage. When exposed to high temperatures, plastic bags can melt and fuse together. This can result in the plastic sticking to the stored items, causing a challenging and potentially damaging removal process. The heat-sealing process, commonly used in manufacturing and food packaging, involves melting the plastic material to create a seal. While this is advantageous for creating airtight seals, it can also lead to unwanted melting if exposed to high temperatures during storage.
To mitigate the potential issues caused by heat retention in plastic bags, it is recommended to use alternative storage methods for silver. Tarnish-resistant fabric or materials specifically designed to prevent tarnishing, such as felt, flannel, or specialty cloth, are ideal. These materials create a barrier between the silver and the surrounding air, slowing down the tarnishing process. Additionally, storing silver in a cool, stable environment away from extreme temperature fluctuations, high heat, and direct sunlight can help maintain its longevity.
While some sources suggest using food-grade plastic bags for storing silver, it is important to exercise caution. The release of acidic fumes and sulfur from aging plastic can still occur, even if the bags are approved for food storage. Overall, it is advisable to avoid storing silver in plastic bags to prevent potential damage caused by heat retention and the release of harmful compounds.

Plastic bags can trap moisture and cause tarnishing
Plastic bags are not ideal for storing silver. While some people store their silver in plastic bags, especially the bags that the silver came in, it is not recommended. This is because plastic contains sulfur and traps moisture, both of which cause tarnishing. Silver is susceptible to tarnishing from moisture and exposure to humidity. As plastic ages, it releases sulfur and acidic fumes that can leave permanent marks on the metal stored in them. Plastic bags without any anti-tarnish protection seal moisture and gases in with your silver, causing tarnishing.
However, some people argue that certain types of plastic bags are safe for storing silver. For example, some sources claim that food-grade plastic bags are safe for storing silver. These include Ziploc bags, which are made of LDPE and approved by the FDA for food storage. Anti-tarnish ziplock bags are also available and are made of non-toxic, non-abrasive materials that protect silver from tarnishing. Vacuum-sealed bags are another option for storing silver, as they block moisture by removing all the air from the bag.
If you choose to store your silver in a plastic bag, it is recommended to use a high-quality, thick bag that can block out heat and moisture. It is also important to note that plastic bags may not provide adequate protection from theft or damage, so it is advisable to store your plastic-covered silver in a more durable and secure container or vault.

Anti-tarnish ziplock bags can protect silver
While some sources advise against storing silver in plastic bags due to the risk of tarnishing, others claim that certain types of plastic bags, such as Ziploc bags, can be used safely. However, the effectiveness of Ziploc bags in preventing tarnish is disputed.
Plastic bags are typically made from petroleum products and contain volatile compounds. When exposed to changes in temperature and humidity, these compounds can leach out and adhere to the silver, causing a challenge to remove them. Additionally, plastic contains sulfur and traps moisture, both of which contribute to the tarnishing of silver. As plastic ages, it releases sulfur and acidic fumes that can leave permanent marks on the metal.
On the other hand, some people argue that as long as the plastic bags are food-safe, made of 100% LDPE (low-density polyethylene), and approved for food storage, they can be used to store silver without causing tarnish. Some users have reported storing their silverware in Ziploc bags for years without any issues. Additionally, most new silverware is packaged in individual plastic bags, either heat-sealed or zip-locked, indicating that this method of storage may not be detrimental to the metal.
To address the concerns about tarnishing, specialty anti-tarnish zip lock bags are available in the market. These bags, such as the Corrosion Intercept® bags, are designed with a revolutionary technology that integrates bonded copper particles into a polymer matrix. This matrix reacts with and neutralizes all corrosive gases, including sulfur and acidic fumes, that come into contact with the bag. These bags provide effective tarnish protection for non-ferrous metals like silver and are also temperature and humidity independent. The bags are inert, non-toxic, and non-abrasive, making them a safe option for storing silver.
In conclusion, while regular plastic bags may not be ideal for storing silver due to the risk of tarnishing, anti-tarnish zip lock bags can provide a safe and effective solution. These specialty bags are designed to neutralize corrosive gases and protect silver from tarnish for extended periods. Therefore, when it comes to storing silver, anti-tarnish zip lock bags can be a reliable option to consider.
