Glass packaging, in the form of jars and bottles, is a chemically inert, impermeable format used for retail honey, preserves and premium food products, valued for its barrier properties and consumer perception but requiring careful handling due to weight and fragility.
In trade practice
Because glass is heavy, transport costs per unit are higher than for plastic or flexible formats, and pallet configurations must account for load stability and breakage risk. Facilities handling glass are expected to operate a glass-in-product prevention programme, including documented breakage procedures and regular audits of glass-handling zones. Closure integrity, typically measured by torque testing, is checked during filling and at intake. Buyers sourcing honey or preserves in glass should confirm that jar and lid specifications, including food-contact compliance of lid liners, are documented.
In a specification
Specifications state jar or bottle capacity, neck finish, closure type and torque range, glass colour where relevant, and require a declaration of compliance for any food-contact lid liner or coating.
