There are several ways to seal a DVD case with plastic. One common method is shrink-wrapping, which involves cutting plastic to size and sending it through a heat chamber to shrink it around the DVD case. Another method is overwrapping, which is a more automated process that uses machines to cut and heat-seal the plastic, resulting in a Y-shaped fold. Additionally, re-sealable clear plastic bags can be used to protect DVD cases from damage and wear, allowing for repeated use. Some DVD cases also come with a sticker seal on the top, making it easier to identify if a disc is brand new or used.

Resealable plastic bags for DVD cases
Resealable plastic bags are a great way to protect DVD cases from damage and wear. They are often used by stores that resell used DVDs, but they can also be useful for anyone looking to keep their DVDs in good condition. These bags are designed to fit snugly around DVD cases, providing a clear and concise display of the disc's title and artwork while also offering protection from dust, scratches, and other potential hazards.
One option for resealable plastic bags is the AcePlus Peel & Seal product, which comes in packs of 1000 bags designed for 7mm DVD cases. These bags are made of thin economy plastic, making them an affordable option for those with large DVD collections or those looking to resell DVDs. The peel-and-seal design makes it easy to insert and remove DVD cases without having to worry about sticky residue or complicated wrapping processes.
Another similar product is the Maxtek Premium Thick Paper CD/DVD sleeves, which come in black or white and offer a more premium look and feel. These sleeves have a window cut-out, making it easy to see the DVD's title and artwork, and a flap that securely closes with a resealable adhesive. While these sleeves don't offer the same level of clarity as plastic bags, they provide a sturdier option that can better protect DVDs during transport or in environments where they may be prone to damage.
When deciding between resealable plastic bags and other forms of DVD wrapping, such as shrink-wrap or overwrap, it's important to consider the benefits of each. Resealable bags are convenient because they can be easily opened and closed without damaging the packaging, making them ideal for DVDs that are frequently used or displayed. They also tend to have smoother edges and a softer feel compared to the often thick and brittle texture of shrink-wrap. Overwrap, on the other hand, is considered a more professional option as it is typically used for new DVDs and has that familiar "Y-fold" look. Ultimately, the choice depends on the specific needs and preferences of the DVD owner or reseller.

Using stickers to seal DVD cases
Stickers are commonly used to seal DVD cases, often as part of a larger plastic wrapping or shrink-wrap. These stickers can serve a security function, helping to identify if a DVD case has been tampered with or opened previously. They also provide information about the DVD, such as the movie's title, barcode, and special features.
Some people choose to remove these stickers after purchasing the DVD, as they can be seen as eyesores or destructive to the packaging. The process of removing stickers can be challenging, often requiring specific tools and techniques to avoid damaging the DVD case. This includes using products like Goo Gone, Scotch tape, razors, or lighter fluids to remove the sticker and any residual glue.
For those who collect DVDs or intend to resell them, keeping the stickers intact is important. Some collectors choose to remove the stickers but keep them inside the DVD case as a memento or proof of authenticity. This practice ensures that the DVD can be resold in "like-new" condition, which may increase its value.
Overall, stickers play a significant role in sealing DVD cases, providing security and information for consumers. While some may find them bothersome and prefer to remove them, others recognize their value and opt to keep them intact or stored within the case.

Automated vs manual shrink-wrapping
Shrink-wrapping is a common method used to package products in a protective plastic film. The process involves enclosing the product in a plastic film and then applying heat, which causes the film to shrink tightly over the product. This can be done manually, semi-automatically, or fully automatically.
Manual shrink-wrapping machines are hand-operated, requiring an operator to wrap the product with film and then manually move it to a heat source. This method is affordable, but the consistency and efficiency of the process depend on the operator, and it is generally slower, packaging only one or two products per minute.
Semi-automatic shrink-wrapping machines automate the sealing and shrinking process but require an operator to place the products in the film. Some semi-automatic machines have additional features, such as magnetic hold-downs, to assist with the process and improve efficiency. These machines can package a product every 30 seconds to one minute and are suitable for lower-volume packaging operations.
Fully automatic shrink-wrapping machines handle the entire process from product insertion to film wrapping, sealing, and shrinking, without human intervention. These machines use photo eyes or lasers to detect products and can package up to 30 products per minute, making them suitable for high-volume packaging operations. Different styles of automatic machines, such as L-bar sealers and side sealers, are available depending on the product dimensions and the specific application.
When deciding between manual, semi-automatic, and fully automatic shrink-wrapping, considerations include cost, packaging volume, product size, and desired level of automation. For example, DVD cases can be sealed using manual methods or semi-automatic machines, as these products are typically packaged in smaller volumes. In contrast, high-volume packaging operations with tens of thousands of products would benefit from fully automatic machines to increase efficiency and reduce packaging costs.

Overwrap vs shrink-wrap
Overwrap and shrink wrap are two popular methods for packaging products in plastic wrap. Both wrapping styles can be used for individual pack wrapping or multi-pack collations. However, there are distinct differences between the two in terms of the materials used, the wrapping process, appearance, cost, and suitability for different products.
Materials
Overwrap uses BOPP (biaxially oriented polypropylene) film, a type of polyethylene film, whereas shrink wrap uses Polyolefin.
Wrapping Process
For overwrap, the film is pre-cut to the correct width for the product. The machine then pulls and cuts the film to the correct length, and the ends of the film are tucked and folded to create a neat, diamond-shaped envelope finish. In contrast, shrink wrap uses a centre-folded PO film that is placed inside an L-shaped sealer machine to create a bag. The bag is then shrunk using a heat tunnel to fit the product.
Appearance
Overwrap provides a more professional and polished appearance than shrink wrap. The tucked and folded edges of overwrap create a neat and precise finish. On the other hand, shrink wrap can result in rough seams and curled or spiked edges, giving a less refined look.
Cost
Shrink wrap tends to be more expensive than overwrap, with a higher cost per pound. Overwrap uses less material and generates less waste, making it a more cost-effective option.
Suitability for Products
Overwrap is ideal for products with consistent shapes, such as DVDs or CD cases, as it requires specific machinery suited to the product's dimensions. Shrink wrap is more versatile and suitable for products with unusual shapes or larger items, as it can accommodate various sizes.

Soft vs brittle plastic wrap
Plastic wrap is a general term used to refer to many different materials. The type of plastic wrap used for sealing DVD cases is typically thin and resealable, such as the AcePlus Peel & Seal Resealable Plastic OPP Bag. This type of plastic wrap is designed to protect DVD cases from damage and wear and can be reused multiple times.
When choosing a plastic wrap for sealing DVD cases, it is important to consider the softness or brittleness of the material. Soft plastic wraps are often made from materials like low-density polyethylene (LDPE), which is considered safer for human health and the environment. LDPE wrap is commonly used for food packaging as it can be safely used in the microwave and provides adequate protection for food items. However, one drawback of LDPE wrap is that it does not provide the same level of cling as other types of plastic wrap, such as polyvinylidene chloride (PVdC) wrap.
On the other hand, brittle plastic wraps are typically made from materials like PVdC, which has stronger cling properties. PVdC wrap is effective in protecting and preserving food items by creating a barrier against chemicals, biological contaminants, and physical damage. However, due to environmental concerns associated with the use of chloride, some brands have switched to alternative formulations, such as LDPE.
The choice between soft and brittle plastic wrap depends on the specific needs and preferences of the user. Soft plastic wrap, such as LDPE, is ideal for those who prioritize health and environmental considerations, while brittle plastic wrap, like PVdC, may be preferred by those who require stronger cling and protection for their DVD cases.
To enhance the durability of plastic wrap, especially in the context of wire wrapping, individuals have experimented with treatments like plasti-dip spraying and liquid Flex Seal dipping. These methods aim to mitigate the brittleness and disintegration commonly experienced with plastic wire wrapping in high-temperature environments, such as under the hood of a car.

Frequently asked questions
There are a few ways to seal a DVD case with plastic. One way is to use a resealable plastic bag, such as the AcePlus Peel & Seal Resealable Plastic OPP Bag, which is designed to fit DVD cases and can be reused. Another way is to use shrink-wrap, which involves cutting the plastic to size with a hot wire and then sending it through a heat chamber on a conveyor belt. This process can be done manually or automatically.
Shrink-wrapping is a process where plastic is cut to size and then heated so that it moulds around the object being wrapped. There are at least two types of shrink wrap: one is thin and stretchy, and the other is thicker and rougher, similar to a shiny comic book bag.
Overwrap is a more professional type of DVD wrap that is only done in automated machines. It cuts the plastic material and uses heat bars to create the "Y" fold at the corners. This type of wrap is generally thick, brittle, and crispy sounding.
Plastic can be used to seal DVD cases to protect them from damage and wear, and to keep them sealed. It also makes it easier to identify if a DVD is brand new or used, and to see the title of the DVD without having to flip through a rack.
