Bakery Packaging Is a Positioning Decision

A pastry box is opened in front of a customer. That single moment decides whether the packaging reads as premium or as an afterthought. Thermoformed trays sit in the middle of that decision: they hold the product still during transport, present it cleanly when opened, and cost little enough to be used at scale.

Shantou Longsheng Industry Co., Ltd. builds multi-station thermoforming machines in Shantou City, Guangdong Province, that produce these formats from PP, PS, HIPS, PET and PLA sheet.

The Formats Bakeries Actually Order

• Mooncake inner trays. Single-cavity trays that cradle each mooncake, with a raised rim for lifting and a base profile that keeps the pastry off the box floor.
• Cake bases. Flat discs with a central support, formed to a consistent diameter so the cake board sits level.
• Egg tart trays. Multi-cavity trays holding six or twelve tarts, with separating walls to stop lateral movement.
• Cookie inserts. Shallow nested cavities that keep biscuits from sliding and breaking.
• Pastry boxes and lids. Rigid transparent lids that turn a simple tray into a display case.

Why Thermoforming Fits Bakery Production

Bakery runs are seasonal and format-heavy. A single thermoforming tool can produce thousands of identical trays per hour, and switching to a different cavity layout means changing the mold rather than rebuilding a process. Because heating, forming, punching and stacking are separate stations, thin display trays and thicker structural trays run on the same machine.

Hygiene matters as much as appearance. Formed trays have no seams or glued joints, so there are no crevices to trap crumbs or cleaning residue.

Material Choice for Bakery

PET gives the glass-clear look that suits open display cases and windowed boxes. PS and HIPS are the economical options for inner trays where the customer never sees the base. PP handles warmer products and is suited where the pack may be reheated. PLA is available for bakeries whose brand requires a compostable claim.

Longsheng, founded in 1998 and holder of 25 authorised patents, supplies precision molds together with its machines and provides installation guidance and operator training, so a bakery packaging converter can bring a new mooncake or tart format online for a season and retire it afterwards.
