Long Paragraph Detailed Version

This food-grade close-it control seal is customized for high-cleanliness sampling scenarios. The special food-safe adhesive has passed comprehensive migration testing for dry, moist and non-fat food categories, complying with global mainstream food contact regulatory systems. The built-in aluminum foil barrier delivers zero vapor transmission rate, effectively preventing sensitive raw materials like pharmaceutical powders and food additives from absorbing water and caking after sampling.

Compared with ordinary packing tape, its high-viscosity backing maintains stable adhesion at low freezing temperatures without falling off. The reserved recording area on each seal enables traceable sampling records, realizing full quality tracking from raw material receiving to finished product delivery. All raw materials and production processes follow EU GMP rules, making it the standard sampling sealing accessory for food factories, pharmaceutical manufacturers, cosmetic labs and third-party testing institutes.

Product Feature

In response to massive customer demand, Bürkle developed the close-it Food & Pharma control seal, a specialized closure sticker equipped with food-approved adhesive. The bonding force is nearly identical to the classic universal close-it seal that has passed millions of industrial verification tests. It tightly covers sampling holes and reliably stops powder, granule and liquid products from leaking out of containers after sampling.

The food-safe adhesive fully meets European food material guidelines and U.S. FDA regulations. Same as standard close-it seals, it adopts an integrated paper-aluminum foil sandwich barrier layer, which forms an airtight seal to isolate moisture, oxygen and external odors, avoiding sample deterioration or deliquescence of hygroscopic raw materials.

Each white seal comes with reserved fill-in writing fields for recording batch number, sampling date, inspector and quality control information. It sticks firmly on plastic barrels, woven sacks, cartons, even slightly damp or frozen container surfaces where ordinary tape fails. Widely applicable to food, pharmaceutical APIs, cosmetic raw materials, food additives and frozen goods sampling procedures, perfectly matching GMP cleanroom and third-party accredited laboratory quality management standards. Each roll contains 500 independent square control seals for continuous mass sampling work.

Bürkle 5303-2018 close-it Food & Pharma seal, 95x95mm aluminum foil barrier, food-safe adhesive compliant with FDA & EU food standards. Hermetic anti-leak for food, pharma, cosmetic & frozen sampling, 500 pieces per roll.
