A lap seal is commonly used in packaging applications to combine two layers or panels of material. This seal is created by overlaying one material panel over another and sealing the two layers along the overlap, or lap, area. Lip seals are used in various industries, including food and beverage, pharmaceutical, and consumer goods, to protect products and ensure that they are adequately sealed and protected during storage and transport.

Several lap seals can be used in packaging, including heat and pressure-sensitive lap seals. Heat seal lap seals are created using heat and pressure to melt the material in the overlap area, creating a solid bond between the two layers. This type of lap seal is commonly used for flexible packaging materials such as films, foils, and laminates. On the other hand, pressure-sensitive lap seals use an adhesive to bond the two layers together. This lap seal is often used for packaging applications where a strong seal is not required, such as for labeling or branding purposes.

One of the critical benefits of lap seals is that they can be created quickly and efficiently using automated sealing equipment. This makes them a popular choice for high-volume packaging operations where speed and efficiency are important considerations. Lap seals can also be customized to meet the specific needs of a particular packaging application, such as by using different materials or adhesives to achieve the desired level of strength and sealing performance.

Lap seals are widely used in packaging due to their simplicity and effectiveness. They provide a secure seal that helps to protect products and maintain their integrity during storage and transport, ensuring that they reach their destination in good condition.

K-Seal and K-Seal Ultimate are both products designed to seal leaks in the cooling systems of vehicles. Both products are formulated with a blend of fibers, resins, and other ingredients that are designed to stop leaks and prevent them from reoccurring. However, some differences between the two products make one a better choice than the other, depending on your specific needs.

Differences in Composition: One of the main differences between K-Seal and K-Seal Ultimate is their composition. K-Seal is formulated with a blend of fibers and resins designed to seal leaks in a vehicle’s cooling system. On the other hand, K-Seal Ultimate is developed with a mix of fibers, waxes, and other ingredients designed to seal leaks and prevent them from reoccurring.

Performance: Another difference between the two products is their performance. K-Seal is designed to seal leaks in the cooling system and stop them from reoccurring. However, it is only guaranteed to work on some types of leaks and may not work on severe or ongoing leaks. On the other hand, K-Seal Ultimate is designed to seal even the most potent and constant leaks in the cooling system and prevent them from reoccurring. It can also seal multiple leaks at once and is compatible with all types of antifreeze.

Ease of Use: K-Seal and K-Seal Ultimate are relatively easy to use. They come in a liquid form that can be poured directly into a vehicle’s radiator. However, K-Seal Ultimate has an applicator hose that allows for easier and more precise application.

Price: In terms of price, K-Seal Ultimate is generally more expensive than K-Seal. This is because it is formulated with more advanced ingredients and is designed to perform better than K-Seal.

Overall, both K-Seal and K-Seal Ultimate are effective at sealing leaks in a vehicle’s cooling system. However, K-Seal Ultimate is generally considered to be the better choice due to its ability to fill even the most severe and ongoing leaks and prevent them from reoccurring. It is also more expensive than K-Seal. Ultimately, the choice between the two products will depend on your specific needs and budget.

Side Seal Bags – sometimes referred to in the trade as Side Weld Bags, are constructed from slit sheeting of either Polyethylene or Polypropylene Film. The film is folded in a desired dimension along one side to suit the fill capacity and length of the bag needed.

A side seal bag, also known as a pillow bag, is a type of packaging commonly used for a wide range of products, including food items, consumer goods, and industrial products. The bag seals the edges of a flat tube of plastic or other material, creating a pouch with a sealed bottom and two open ends. The bag can then be filled with a product, and the loose ends can be closed to create a secure and protective package.


A side seal bag is made using a flat tube of flexible material, such as plastic, paper, or foil. This tube can be created using various methods, including blow molding, extrusion, and lamination. The material used for the bag will depend on the product being packaged and the desired properties of the bag, such as barrier properties, strength, and durability.

Once the flat tube is created, it is sealed along the edges, making a pouch with a closed bottom and two open ends. The loose ends can be left open for filling or pre-sealed to create a bag with a reclosable or tamper-evident seal.

Filling and Sealing

The bag is then filled with the product, and the open ends are sealed. This can be done by heat sealing, ultrasonic welding, or other methods depending on the type of material used for the bag and the properties of the product being packaged. The sealing process creates a secure and protective package for the product.

The side seal bags are standard and versatile because they can be made using various materials, like Plastic, Polyethylene, Polypropylene, Kraft paper, and aluminum foil. And they can be filled with multiple products, such as Foods, Snacks, Powders, liquids, and many more.


There are several different types of side seal bags, each with its own specific features and applications:

Gusseted Bags: Gusseted side seal bags have expandable pleats on the bottom of the bag, which allows the bag to stand upright when filled and provides extra space for the product. This makes gusseted bags ideal for bulky or irregularly shaped products.

Zipper Bags: Zipper side seal bags have a zipper closure on one end, which allows the bag to be opened and closed multiple times. These bags are ideal for products that need to be accessed multiple times, such as snacks or household items.

Wicketed Bags: Wicketed side seal bags are pre-formed and attached to a wicket, which makes them easy to handle and fill. These bags are often used for industrial products or other items that require automated filling.

Stand-up Pouches: Stand-up pouches are a type of side seal bag that is designed to stand upright when filled. They often have a square or rectangular bottom and a curved top, which makes them easy to display on a shelf. These bags are ideal for products that need to be visible, such as food items or consumer goods.

Vacuum Pouches: Vacuum Pouches are sided seal bags that have been vacuumed sealed to remove air and preserve product freshness; they are mainly used to protect food products, preventing them from oxygen, humidity, and light.

In conclusion, side seal bags are a versatile type of packaging made from various materials and filled with a wide range of products. They are widely used in multiple industries, from food to industrial; due to their versatility and ease of use, they can be produced on a large scale and is a cost-effective solution for many.
