As a casket supplier, I often encounter various questions from customers regarding casket selection and related accessories. One question that frequently comes up is whether it is necessary to use a casket sealer. In this blog post, I'll delve into this topic, exploring the pros and cons of using a casket sealer to help you make an informed decision.

What is a Casket Sealer?

A casket sealer, also known as a gasket or a sealer ring, is a rubber or silicone device designed to create an airtight and watertight seal around the edges of a casket. When the casket lid is closed, the sealer compresses against the rim, preventing air, moisture, and other elements from entering the casket.

The Case for Using a Casket Sealer

Preservation of the Body

One of the primary reasons people consider using a casket sealer is to preserve the body for a longer period. By creating an airtight seal, the sealer helps to slow down the decomposition process. This can be particularly important in cases where the viewing or visitation period is extended, or when the funeral is delayed due to logistical reasons. For example, if a family member passes away in a foreign country and it takes time to transport the body back home, a casket sealer can help maintain the body's appearance until the funeral service.

Protection Against External Elements

Another benefit of using a casket sealer is that it protects the body from external elements such as dirt, insects, and groundwater. In some burial sites, there may be a risk of flooding or water seepage. A casket sealer can prevent water from entering the casket and causing damage to the body. Similarly, it can keep out insects and other pests that could potentially cause harm.

Aesthetics

A casket sealer can also contribute to the overall aesthetics of the casket. When the lid is closed with a proper seal, the casket looks more finished and professional. This can be important for families who want to provide a respectful and dignified final resting place for their loved ones.

The Case Against Using a Casket Sealer

Environmental Concerns

One of the main arguments against using a casket sealer is its environmental impact. Most casket sealers are made from synthetic materials such as rubber or silicone, which are not biodegradable. When the casket is buried, these materials can persist in the soil for a long time, contributing to environmental pollution. For those who are environmentally conscious, there are alternative options available, such as Biodegradable Funeral Plant Wicker Weaving Wicker Coffin Casket Bed Customized Size European Style 6 Handles Custom-made 7 Days that do not require a sealer.

Cost

Casket sealers can add to the overall cost of the casket. Depending on the quality and type of sealer, the price can range from a few dollars to several hundred dollars. For some families on a tight budget, this additional expense may not be necessary.

Cultural and Religious Beliefs

In some cultures and religions, the use of a casket sealer may not be in line with traditional beliefs. For example, some religious traditions believe in a natural and immediate return to the earth, and the use of a sealer to delay decomposition may be seen as going against this principle.

Making the Decision

Ultimately, the decision of whether to use a casket sealer depends on several factors, including personal preferences, cultural and religious beliefs, environmental concerns, and budget. If preservation of the body is a top priority, and the family is not overly concerned about the environmental impact or cost, then a casket sealer may be a suitable option. On the other hand, if environmental sustainability is important, or if the family adheres to a religious or cultural tradition that discourages the use of sealers, then alternative caskets such as Seagrass Coffin Green Funeral Coffin Wicker Tecosinte Casket Biodegradation Willow Coffin Cornskin Coffin may be more appropriate.
