Differences between Roll Film and Ready – to – use Bags in Packaging
Roll Film
Roll film comes in the form of continuous plastic film rolls. For packaging, it depends on specialized machinery. The process involves bag – making, filling, and sealing. The resulting bags typically have a regular and simple look, mainly three – side – sealed or four – side – sealed. This simple bag – type is beneficial for large – scale production as it ensures uniform appearance for each bag. It suits food companies aiming for high – efficiency and consistent packaging, like those packaging mass – produced potato chips or biscuits.
Ready – to – use Bags
Ready – to – use Bags are pre – made in various shapes. They include common types such as three – side – sealed bags, stand – up pouches, zipper bags, and even customized shaped bags according to product needs. In terms of appearance design, there’s a lot of flexibility. Food businesses can design unique bag types and add eye – catching printed patterns based on product features and market trends. For instance, a fruit gummy for kids might use a cartoon – shaped bag to attract children, making it ideal for products that require good appearance display and brand building, like high – end chocolates or specialty snacks.
Roll Film
Roll film is great for packaging foods with good fluidity. For granular foods like nuts and beans, the packaging equipment can accurately control the filling amount and complete the packaging quickly. In powdered food packaging, such as milk powder and coffee powder, it can prevent powder leakage and keep the package airtight to avoid dampness. For liquid foods like beverages and sauces, with the right liquid – filling equipment, it can achieve efficient and hygienic packaging. Also, during packaging, the bag – making size can be adjusted according to product needs, whether it’s a small trial – pack or a large family – pack. However, it has limitations for foods with irregular shapes, large weights, or special packaging shape requirements. For example, handmade candies with various shapes or large – volume whole cakes are hard to package tightly with roll film, and the products are easily damaged during handling.
Ready – to – use Bags
Ready – to – use Bags have unique advantages for foods with special shapes or requirements. Stand – up pouches with their special bottom support can make the package stand steadily on the shelf, which is convenient for consumers to pick up and saves shelf space. They are suitable for heavier foods like large – package pet food and products that need to showcase the product image, such as high – end instant oatmeal. Zipper bags are designed for easy multiple – time access by consumers and can better preserve food freshness, so they are perfect for snacks and dried goods. Customized shaped bags can be tailored to the unique shape of the product, like uniquely – shaped candies or toy – shaped foods, protecting the product and attracting consumers with their unique look.
Roll Film
Regarding material procurement, roll film is usually sold in large rolls, and food enterprises can get favorable prices when buying in large quantities. During packaging, the material utilization rate is relatively high with less waste. But using roll – film packaging requires investing in professional machinery, and the equipment purchase cost can be high, ranging from small – sized machines to large – scale automated production lines. Enterprises need to consider their production scale and budget. Additionally, there are regular maintenance costs and potential repair costs due to equipment failures. Every time the packaging product specifications or bag types change, professional technicians are needed to re – debug the equipment, which takes time and may cause production stoppages, increasing production costs.
Ready – to – use Bags
Since Ready – to – use Bags are pre – made, their production costs are relatively high. The bag – making process involves manual operation and mold use, with labor and mold costs accounting for a large part. Different shapes and sizes of bags need customized molds, and mold development and production costs are not low. However, for small – scale production or enterprises with limited packaging equipment investment, using Ready – to – use Bags has advantages. They don’t need to spend a lot on professional packaging equipment. Simple filling and sealing equipment are sufficient, and some products can even be filled and sealed manually, reducing upfront equipment investment. Also, the procurement of Ready – to – use Bags is flexible, allowing enterprises to buy according to order quantity, avoiding equipment idleness and having better overall cost control.
Roll Film
The packaging process of roll film depends on professional equipment, so operators need a high technical level. They must be familiar with equipment operation, debugging, and troubleshooting to ensure smooth packaging. When changing packaging product specifications, such as bag size, filling amount, or bag type, professional technicians often need to spend a long time re – debugging the equipment. For example, when switching from small – sized coffee powder bags to large – sized coffee bean bags, multiple equipment parameters need to be precisely adjusted. This not only takes time but may also lead to packaging quality problems due to improper debugging, affecting production progress and resulting in low production flexibility.
Ready – to – use Bags
Using Ready – to – use Bags is relatively simple. After receiving the bags, enterprises only need to fill the products and seal them. The equipment requirements are low. Common sealing equipment like heat – sealers and impulse sealers are easy to operate and master, even for those without professional packaging experience. During production, if the packaging product changes, only the corresponding bag specifications and types need to be changed, without complex equipment debugging. It can quickly adapt to different product packaging needs, showing high production flexibility. For example, a small – sized food enterprise that originally used three – side – sealed Ready – to – use Bags for nut – based snacks can quickly switch to using suitable bags for new fruit – preserved products, shortening the new product launch cycle.
