In carton sealing tape, the adhesive system governs seal reliability more than any other component — more than backing, more than width. The three chemistries most commonly used in carton sealing tape are hot melt (synthetic rubber), water-based acrylic, and natural rubber. They differ in tack, shear, temperature behavior and aging in ways that decide whether a carton stays sealed through th...
Tape doesn’t spoil like milk. It goes bad quietly — a little less tack each month, a little more ooze each summer — until the day seals start failing and nobody can say what changed. This playbook gives your warehouse five rules that keep tape performing the way its TDS says it should. Rule 1 — Keep it between 4 and 26°C Cold is a common cause of seal failure. Below abo...
A supplier’s TDS tells you what the tape did in a laboratory. It does not tell you what the tape will do on your cartons, in your dust, through your winter. Before you approve a supplier — or accept a full container — run these three bench tests. They take under two hours of hands-on work, spread over 72 hours, need no special equipment, and catch the failures that actually cost ...
Comparing tape by price per roll is how shippers overpay. A cheaper roll that needs two strips per carton, stalls the case sealer, or lets go in a cold warehouse costs more per sealed carton than the “expensive” alternative. Cost per sealed carton is the only honest comparison. Here is how to run it for the two dominant options: water-activated kraft tape (WAT) and BOPP pressure-sensit...
On an automatic case sealer, the tape is part of the machine. Operators blame the sealer for jams; often the sealer is fine and the roll is wrong — wrong core, wrong outer diameter, wrong unwind tension. Specifying tape for machine application is a different job than specifying tape for a hand gun. This guide covers the four specs that decide whether the machine runs or stops. 1. Roll geomet...
The global plastics treaty is moving again. After the delegations' meeting in Bangkok on September 27–30, 2026, the Intergovernmental Negotiating Committee chair is expected to release a second iteration of his 'Aid to Negotiations' text ahead of INC-5.4, and the resumed negotiating session (INC-5.4) is now on the calendar for March 2027. No final treaty exists yet, but the direction of trav...
Every carton you ship is a billboard you already paid for. Custom printed tape puts your logo, handling marks, or brand colors on every box at a fraction of the cost of printed cartons — but only if you specify it correctly. Washed-out prints, off-brand colors, and pallets of unusable tape usually trace back to the same handful of specification mistakes. This guide walks through them in the ...
A sealed carton is only as secure as its seal. Standard packing tape can be peeled, the contents accessed, and the tape smoothed back down — leaving no trace. Tamper-evident tape changes the equation: it does not stop anyone from opening the carton, but it makes sure you know someone did. This guide explains the three mechanisms, when they are worth the premium, and their limits. 1. The thre...
The cheapest quote is rarely the cheapest tape. When three suppliers quote “the same” carton sealing tape at three different prices, the specs behind those prices are usually not the same at all — different units, different test methods, different things left unsaid. Some of it is innocent; some of it is not. Either way, here is how to normalize competing quotes before you compar...
