| Horizontal flow wrapper | Discrete, generally uniform products such as bars, bakery items, hardware, and medical or consumer goods suitable for feeding in a line. | Individual packs formed from a continuous web, commonly with a longitudinal fin seal and end seals. | Heat-sealable flexible films; the appropriate film structure depends on barrier, seal, appearance, and product requirements. | Product dimensions and orientation; infeed spacing; film tracking; seal temperature, pressure, and dwell time; required line speed. | Continuous operation can suit high-volume production of consistently shaped products; the film can provide a close-fitting pack. | Irregular, fragile, or sticky products may need special feeding or product handling. Confirm that the product can be reliably spaced and that the selected film seals on the machine. |
| Vertical form-fill-seal wrapper | Free-flowing or portioned products such as grains, powders, snacks, and small components that can be dosed into a forming tube. | Flexible bags, including pillow-style packs and other machine-supported bag formats. | Rollstock films selected for product protection, sealing performance, and compatibility with the forming and dosing system. | Product flow and dust; dosing accuracy; bag dimensions; film unwind and registration; seal-jaw settings; cleaning and changeover needs. | Combines bag forming, filling, and sealing in one process and can handle a range of fillable products. | Product flowability and accurate dosing are critical. Dust, sharp pieces, or product trapped in the seal area can affect seal quality and uptime. |
| Shrink wrapper with heat tunnel | Multipacks, grouped containers, cartons, and products that can tolerate a controlled heat-shrinking process. | Film-wrapped single items or grouped products; some configurations use a tray or pad for support. | Shrink film selected for the product, pack appearance, load stability, and process conditions. | Product heat sensitivity; pack geometry; tunnel temperature and airflow; conveyor speed; ventilation; guarding and heat safety. | Can create a close-fitting bundle and help keep grouped items together for handling and display. | Heat exposure may be unsuitable for temperature-sensitive goods. Film selection and tunnel settings affect shrink, appearance, and package integrity. |
| Stretch wrapper for unit loads | Palletized cartons, totes, and other stable loads prepared for storage or transport. | Film wrapped around a pallet load, typically with overlapping layers and a secured film tail. | Stretch film compatible with the wrapper’s film carriage and the load’s containment needs. | Load dimensions, weight, stability, and pallet condition; wrapping pattern; film tension or pre-stretch settings; floor space and operator access. | Can secure multiple items into a unit load and help protect them from dust and handling contact during distribution. | Does not make a load waterproof or replace sound palletizing. Confirm containment needs without crushing cartons or destabilizing the load. |
| Banding wrapper | Printed materials, cartons, trays, and other products that need a band around one item or a grouped bundle. | A narrow band around the product or bundle rather than a full film enclosure. | Paper or plastic banding material designed for the machine and the required package hold. | Bundle dimensions and compressibility; band width and tension; product surface; desired changeover and feeding method. | Uses a band rather than enclosing the whole product, leaving much of the pack visible and accessible. | Provides less surface coverage than a full wrap. Check whether the band alone supplies sufficient bundle retention and protection for the route to market. |
| Manual or semi-automatic turntable stretch wrapper | Low- to medium-volume pallet operations with loads that can be safely placed on a rotating turntable. | Stretch film applied around a pallet load as the turntable rotates; some models automate parts of the cycle. | Stretch film matched to the carriage and required load containment. | Available floor space; pallet size and load weight; operator handling; turntable clearance; electrical supply and safety interlocks. | Can reduce repetitive hand wrapping and provide more repeatable wrapping patterns than fully manual wrapping. | Turntable capacity and load stability must be checked. Loading and unloading arrangements, operator training, and guarding affect safe operation. |
